INTRODUCTION: The book under review contains a very extensive description of
var ious pressure casting methods in current use, The .6uthor treats these
various methods in a very thorough rjanner and attempts to evaluate and to
compare them to other metal forming 'processes, while pointing out future
possibilities for their improvement and development. The the casting methods
- hot and cold chamber - will be treated only.cursorily in this review as they
do not appear to differ substantially from the methods known and used in this
country for'many years. The chief emphasis in this review will be placed on
two high-density casting processes: crystallization under pressure, and the
"compression molding of molten metal," These two methods which appear to be
emerging from the experimental state in the USSR are claimed to have nmerous
advantages over the casting and forging. According to the author compression
MTV of molten metal differs substantially from the casting, although

'in some respects and at certain stages it is similar to the cold-chamber the casting
process. As the principles of compression molding are applied in this country to
the manufacture of thermosetting plastic parts, the Russian term "shtsmpovk0-
literally press-forming - was translated as "compression molding" (of molten metal).
Tn view of their many reputed advantages and possible applications, the methods of
crystallization under pressure and compression molding of molten metal will receive
as thorough a treatment as the scope of this review will permit.

The behavior of metal during the injection process is carefully studied and the
ceases of the fronts.3 impact and the turbulence of metal flow are analyzed.
The author goes on to describe the various casting machines of Soviet and foreign
make, the design and making of dies, and the fundementals of pressure-casting
equipment design,, Space is devoted to the composition, casting temperature and
behavior of some alloys. In conclusion there in a brief review of various
technological problems encountered in the casting. In Chapter XIV the author
discusses the fundamentals of the two novel casting methods, namely, crystalli-
zation under pressure and the compression molding of molten metal. He begins by
enumerating the dravbacks of the casting and the need for a casting process by
vbich dense castings of thin and heavy sections with superior mechanical properties
could successfully be produced. The preliminary conditions and requirements for
such a process are listed and discusEed, follmred by an account of the development
of such methods. The chief difficulties are said to arise during the solidifica-
tion of metal in heavy sections of the casting and in other areas of local
accumulations. Neither heavy gate-systezw nor well designed riser systems can
eliminate shrink cavities or porosity. In evutrast to the hydrodynamic pressure
acting only for a short period of time the hydrostatic pressure may be applied
to the metal during the vhole process of solidification.
Card 3/18
i~i ~- 0~4f-.4. I 441i
To achieve this it is necessary to create such conditions under which, after the
hydrodynamic pressure has ceased (that is, after the mold cavity has been filled),
the pressure of the moving plunger can be made to act on the vhole surface of the
casting until solidification is complete. It is vell known that in homer and
press forging the forming of metal is combined. with its densification, and the
pressure of the deforming force is transmitted to the total surface of the work
piece. Similar processes, which may be likened to semi-forging action, can be
used to form and to densify molten metal. According to the author, such methods
are crystallization under (plunger) pressure, and the compression molding of
molten metal. The basic difference between these two methods is this: in
crystallization under pressure the pressure is applied by a plunger but there
is no flow or displacement of the metal; in compression molding of molten metal
tl~e pressure is also applied by a plungerbut the metal is first set In motion
by the descending plunger and is squeezed out to fill the the cavity before
the plunger begins to exert any compressive force on the metal. The action at
that Point Is similar to impact extrusion. In both cases the pressure is
maintained during the entire period of crystallization, this being the milin
feature of these t-vo methods. As soon as the die cavity Is filled under
pressure the metal flow comes momentarily to a standstill_, causing hydraulic
homer. This hydrodynmde pressure is instrumental in forming the sharp
contours of the casting and also helps to densify the metal.

Pressure Casting
The hydrodynamic pressure lasts only for a fraction oi a second. It then becows
constant and the actual process of "pressing" or semi-,forging begins. The fall
pressure of the press begins to act on the metal, increasing its density as the
metal crystallizes under pressure and, later, depending: on the- nmelfie- pressure
applied, the metal is further densified during plastieLdeformation. To sunmarize,
these two methods differ from the castings in the kinematics of metal flov and
in their ability to densify the metal. Below is a brief description of these
two novel casting methods.

Pressure Casting
2mrlesslon mold"Ma Of ADIten metal . To obtain large thin-valled castings of
complex configuration It has become mandatory to form the metal under a pressure
acting on the whole outface or casting. External pressure molding Is regarded
as being not quite suitable for this purpose as, according to the author,
crystallization of the metal takes place basically without pressure. Instead
of filling a preasseabled and closed die through a gate where the metal
solidifies rapidly and cuts off the casting from the source of metal and pressure,
the forming and solidification of metal should take place under continuous
omaidirectional high pressure exerted by the plunger. To meet such conditions
the metal should not be charged Into a separate pressure chamber as It is done
in the casting but it should be ladled directly into the the and then forced by
the descending plunger into the space formed by the clearance between the the
walls and the plunger in the closed position, thus determining the shape of
the casting (see Fig. 172, card 15).
The compression molding process Is described as follows:
1, A carefully neamu*ed amount of molten metal In "ad' d directly into an
open preheated and coated the cavity.
2. Pressure is app3ted to the metal by a moving plunger activated by a
hydrmlic press, displacing some of the metal and pressing It tightly
against the confining vans of the the vith an upward displacement.
The pressure is maintained until crystallization is complete. The
plunger Is then vithdrmm and the casting ejected.

2. No air can be entrapped in the open the became of the lower speed of
metal flow.
3. In the casting the metal enters the the through a side gate, striking
the opposite wall and dissipating the hydrodynamic pressure. In
compression molding the metal flows through the whole cross section of
the cavity parallel to the the valls without any turbulence. The
hydraulic hamer occurs when the metal flow stops and helps to produce
sharp contours and a denser casting.

Pressure Casting
Various hollow shapes which am said to be most suitable for compression molding may
require in some cases a special approach. Parts with a small central cavity are
produced by displacing a wal I volume of metal. Finned hollow parts require a
molten metal basin below the casting configuration (see Fig. 209).' The ratio of the
volume of the part to the volume of the cavity determines the speed with which the
metal is displaced. In molding of shaped castings such as turbine blades, careful
metering of the metal is said to be essential, Turbine blades which must be held
to close tolerances (plus or minus 0.2 m) without machining require extremely
careful metering of metal,, as an overdose will produce a thick and innacurate profile
(see Fig. 214). Another factor claimed to be of importance is the ratio of the.total
area of contact with the die to the volume of the part. A large area of contact with
the die will cause rapid cooling of the metal; this in turn calls for hiaher pressure.
To produce flat and, especially, annular shapes closed-dies are usedpad the method
itself resembles the cold-chamber die casting bothod, o30 transfer noldingas employed
in,the p3awtics industry (see Fig, 215)., According to the author, however, the method
possesses numerous advantages over the cold-chamber method., there-the metal enters
the die through a side gate from a separate pressure chamber. These are its reputed
advantages:
1, relatively slow fl-Dw of metal reduces the erosion of dies and prolongs their
service life.

Pressure Casting
2. The metal flows more orderly and remait free of impurities as it is
squeezed out from the bottom of the cavity,
3. The metal receives the required velocity at the very beginning of the
forced flow which permits the use of heavy gating to transmit the
necessary higb pressure to densify the casting. In this method hydraulic
hammer oacurs towards the end of the metil flow causing hi*i back
pressures in the die. The metal should be forced into a closed the
under high specific pressure (on the order of IODO kg/sq cm). If the
part has some heavy sections far from the Soft additional risers must
be provided,
Havift discussed in previous chapter# the technolM of compression molding of
molten metal., the author proceeds to discuss in Chapter = and XX the operatiq;ml
requirements for successful compression molding of molten metal. Below, some ..
figures are given pertaining to the casting regimes of these new methods, These
figures are said to be the result of numerous tests and experiments conducted by
Soviet scientists and engineers. In compression molding of molten metal it is
important to preheat the dies to the right temperature which is said to vary from
100*C to 3500C, depending on the metal. The following figures are given for the
optIm- temperature of metal during casting: brass at 900-950*C; silumin at
6oo-650*C. To avoid turbulence of flov and entrapment of air the plunger speed
mist be carefully estimated and maintained. For small parts the plunger speed is
given as 0.2-0A meters per second, and 0.1 meters par second for large parts.

At 0.8 meters per second and over, there is a danger of turbulent flow and air

equipment. Some specialized presses vith miltiple cylinders are reported to be

under development or in the experimental stage-. Various machines are said to be
easily adaptable for these methods (see Fig.238 anc 237). The compression molding

These madbi s,vmlike other types, do not have a separate pressure chamber and
the metal nay be poured directly into the cavity. The parting line of the the
coincides vith the axis of the moving plunger. This feature makes it possible
to use these machines for compression molding of molten metal. Other pieces of
equilment described are various distributing arrangements and furnaces for the
preparation of melt.
In the last chapters - XXII to XXV - the author deals vith production planning
and the organization of casting houses for the various aforementioned casting
metlods. In conclusion he attempts to present some of the economic advantages
to be gained by employing these two new methods. The savings in metal alone are
reputed to be at least 30 percent and may be as high as 75-80 percent in the
case of sm-11 parts vhIch ordinarily have to be machined :erom solid blanks.
Also saw sectionally manufactured peqts can be cast in one piece by the
compression molding method, Some cast iron parts, according to the text, may
be made from zinc alloys more cheaply and rapidly, although the original cost
of miLterial is hi*ier. It Is further reported that vhen one of the large plants
adopted the crystallization under pressure method the material requirements were
reduced from 80 to 25 tons a monfli. VRil-okiq ben'11-111A PSI't"t n10101wil 11PNIZ of

Having cited the above instance the author concludes that compression molding is
hi*Lly indtable for the manufacture of smal I bushings and bearing rings. Finally,
it Is stated that in spite of its certain disadvantages, die casting should not be
replaced by compression molding and crystallization under pressure as these two
methods should be reserved for high-integrity solid and thick-valled castings and
castings for hi& pressure service.
MOW, As far as it can be judged from the information on hand the two casting
methods discussed above are not currently employed in the United States, Although
compression molding can be compared to cold-chamber die casting vhere high pressures
are also exerted on the metal during solidification and early stages of cooling so
as to produce a dower structure, the author claim that there are several
differences between these two methods; it is also said that compression:mDlding has
several definite advantages over cold-chamber the casting. From the text alone it
is hard to determine the practical difficulties and the engineering problems
connected with this casting method. Furthermore, all the figutres mentioned in
this review, as well as the arguments in favor of crystal3ization under pressure
and the compression molding of molten metal, come from a Russian source and, as
far as it is known, have not been verified by an independent source,

ABSTRACT: The drawbacks of diecasting (DC) and means for eliminating
them are examined, also liquid die-stamping and the process of
cry-stalization under piston pressure. The major drawbacks of
diecasting are the inclusions of air. Thin-walled castings, free
of air inclusions, may be obtained with a rational pouring system
(PS), but with increasing wall thicknesses the removal of air
from the mold becomes more complicated. A demonstration
using three identical discontinuous patterns with differing PS's
showed the effect of the PS on the mechanik~_-al properties which,
in this instance, differed by 60-80 percent among the patterns.
Measures for the removal of air from the aWfity of the mold may
Card I /Z be summarized a5 follows: a) the design of'a rational ventilation

system; b) the design of a PS which would assist in transferring
the'~air contained in the metal into the ventilation system. For
the elimination of air special distillation reservoirs are used,
into which the initial portions of oxidized metal are conveyed
along with the air. These reservoirs are placed in points most
distant from the inlet sprue. In crystallization under piston
pressure the gases remain in the reservoir and porosity and
blisters are avoided. A forced filling up of void; and blisters by
liquid metal occurs under the pressure action of the piston; the
shrinkage head and the PS are unnecer,5ary. The usable output
reaches 98 percent. This method is employed for pouring of
blanks and ingots. By contrast, for purposes of making more
complex shapes, stamping of liquid metal is employed, and the
filling of the mold is accomplished by means of forcibly pressing
the metal in by means of a punch.

to a pressure die casting die including the casting-in of bosses
and holes. Inaccuracies in certain dimensions (mainly height)
are often caused by inexact dosage of metal. More precise
components (such as turbine blades) can be obtained by the
ejection of surplus metal into a riser space. The amount of
surplus metal is nevertheless smaller than in the pressure die

ABSTRACT: During past years research was conducted in the USSR
and abroad on casting the aluminum ally cylinders
of air-cooled engines under pressure. The author
considers the various properties which such an alloy
must have, citing French and German alloys in Table 1.
The author recommends that alloy AL2 be used for
pressure casting of cylinders. Besides aluminum,
the alloy must contain 9 - 11% silicon, 1 - 1.2016

PERIODICAL: Liteynoye proizvodstvo, no.ji.1,961, 6-12
TEXT: - Although die.casting has been,improved considerably, there are
still some drawbacksi.in this method which couldnot ypt be eliminated. The
major.drawback is the formation of air-inclusions,and local surface-defects
owing,to the.whirlin6 or flowing of the metal along the cold walls of the
mold. 'By ensuring a linear velocity of the metal flow with a suitable run-
ner system and subsequent pressing out the air-bubbles from the part of the
mold that is not easily ventilated, air-inclusions do not originate. The
runne.r,system also affects,the service life of the pattern. Studies carried
out.by.the author show that compacting of the metal is of great importance
whereby the air bubbles and blisters can be eliminated. In this connection,
control.of.the metal flow entering the mold is very effective. Therefore)
all factors governing the metal flow: fluidity of the liquid metal, flow of

the metal along the mold wall and the heat balance of the mold are of im-
portance.9 while, at the same time, factors causing the above-mentioned phe-
nomenat excessive velocity, whirling, formation of hydrodynamic resistance
must be eliminated. To determine the effect of these factors, tests were
made with different runner systems for three main types of castings (I. box-
type, II. pipe sockets, III. flat pieces). The experlmental iuray--L, bwiA-ms v4=
designed in such a way, that the thickness of the riser could be varied
(from 0.8 to 6 mm, 4 - 8 and 3 -7 mm). To investigate the metal flow, me-
tal was poured in from different sides of,the mold and in various directions
(perpendicularly, tangentially) to the core, (Figs. I and 5). Based on the
numerous experiments carried out under varying.conditions it was established
that with hydraulic casting machines, developing a high specific pressure,
it is possible to fill the mold adequately, with a wide range of cross sec-
tions of the runner (from I mm to the wall thickness of the casting). For
thin-walled castings.runners with small cross seotionsehould be used,
since, generally, the larger the cross section of the riser, the greater th3
possibility of controlling the metal flow and of reducing whirling. However,
in spite of the larger cross section of the feeder gate, the required high
velocity of metal flow must be attained. In modern die casting machines

with horizontal pressure chambers this is easy to-ensure, as the speed of the
pressing piston can be regulated within a wide range. Hence, the conven-
tional method of.increasing the pouring rate by reducing the cross section
of the riser can be dispensed with. It is possible to arrive at an optimum
runner system, by controlling the piston speed and increasing the riser cross
section. By these measures the development.of friction and hydrodynamic re-
sistance will be prevented. When the piston speed, (w, in m/sec), the die
cross-sectional area (P).and the:optimum riser-seotion.(f) are known, the

zation is accelerated. The tests made in three,groups with three main types
of castings proved that in nearly.all-cases the bigger.riser diameter,Savour-
ably affected the quality of castings, when.the-metal flow was introduced
from various sides of the mold and at different.angles,. as long as casting,
'Was carried-out withou't frontal impact. All-the.experimental and industrial-
scale-ca6tings proved that although'the in-rease in the riser cross section
reduces whirling, increases the life of the mold and helps to reduce air-en-
.closures, all these positive effects-are obtained.only when,the increase*in
riser-crbss section,is accompanied by the proper direction of the,metal
flow- Nor has the riser cross section any.influence on the pouring time,
as this depends on machine-capacity. The optimum riser cross section should
be as near to the wall thickness of the casting as possible., The basic.
principle in designing the runner,system is t,o control the metal flow and to
design a system which will eliminate whirling and.ventilate the large hol-
lows in the mold. Recent types of runner systems try to el'iminate the re-
current metal flow and to bill the difficult to ventilate areas of the mold
in the first.place4;. Three types of runner systems are mentioned: vertical-
lateral risers, controlled risers and a,version of the central runner system

TITLE: Trends in the construction of machines for the
manufacture of close-grained castings
PERIODICAL: Vestnik mashinostroyeniya, no. 6, 1961, 46-50
TEXT: Close-grained castings are often used instead of forgings and
hot stampings, the mainreason being a metal saving of 55-70%. However,
in the absence of the mass production of special machines, some firms
carry out this special casting process in universal equipment. Within
the last 15 years, 4 types of special machine for close-grained casting
have been released in small batches. Production experience with them
has resulted in determining the field of application of this type of
casting* However, the further development and adoption of these pro-
cesses has been retarded owing to the absence of machines designed on
the basis of long-term production experience. The universal casting
machine YJf11__)1-2(UL%1-2) represents a combination of 2 hydraulic prosses,

This machine has been modernized. All control operations are carried
out hydraulically. Cross sections of modernized ULM-2 type machines
for various methods of close-grained castings are illustrated. In
all cases where the pressure acting on the form grip is insufficient,
wedge type or clamp type grips (Fig. 5) are successfully used. There

ABSTRACT: Compacting differs from casting ynder pressure in that the first is
carried out under hydrostatic pressure which does not stop until the cast hardens
completely. The present investigation considers the problem of compacting casts
depending on the thermal processes during casting. Several sci~:-ntists (Tamman,
Bridgeman, Welter, et al. and later V. A. Bobrov, A. A. Bochvar) have observed
some incroase In the melting temperature of alloys under high pressure. When cry-
stallization proceeds under plunger pressure,,the rapid hardening under pressure,
the close contact with the heat conducting mold, and the lack of gas clearances
lead to intensive overcooling of the alloy. Ali casting defects are eliminated

TITLE: Deformation and mechanism of cavitation of the core

PERIODICAL: Izvestiya vysshikh uchebnykh zavedeniy.
Chernaya metAllurgiya, no.2, 1962, 88-97
TEXT: The authors describe experiments to determine the stress
conditions arising in a billet during cross-rolling, and the
causes of cavitation in its core. For this purpose they used
lead billets into which strain gauges were inserted. Preparation
of billets is described and the results are shown by graphs and
oscillograph recordings illustrating characteristic deformation
of the core, and of different layers of the metal. Due to the
greater speed of flow of the peripheral layers compared with that
of the core and at the ends of the billet, considerable longitudinal
tensile stresses arise in the core. There is also considerable
plastic deformation of the core in the longitudinal direction which
increases as the billet travels through the roll-pass.
As tho billet enters the rolls compressive deformation is observed

Deformation and mechanism ... Eo82/E435
in the peripheral layers of the metal. This changes to a
rapidly increasing longitudinal tensile deformation.
A corresponding change of radial stresses from compression to
tension takes place in the meridional sect-ion of the billet.
In the "plastic cone" area, and in the adj acent metal, compressive
stresses appear in the direction of the external forces but
perpendicular to this, and at an angle, transverse-radial tensile
stresses arise. The plastic displacement of the peripheral
layer relative to the core, increases the tension in the core of
the billet. Maximum inequality of stress and deformation was
observed at the boundaries between the plastic cone and the
eid portions of the billet. Cavitation, due to the influence of
bur~t!;-.g stresses, precedes plastic deformation. When rolling
billets with different ratios of length to diameter, the stress
conditions are analogous, but the magnitude of stress differs.

ITMSLATION.- It has been established aB the result of an investigation that the
optimum temperature interval for the hot rolling of tubes of EP27 steel lies vrithin
the limits of 1150-11800- In heating the tub-- shaped billets, it is necessary to
take into account the heating up of the met'll irk the broaching operation. Hot
rolled tubes of EP27 steel have a sufficient reoerve of ductility for fftl~er co-;d
working without special heat treatment. The inteexmediate and final heat treatment
of the RP27 steel tubes should be carried out by heating them to 1050-1-1001) with a
holding time at this temperature depending on their wall th-Ackness, and by

ABSTRACT: An Author Certificate has been issued describing a method for
rolling pipe on a graduated mandrel (see Fig. 1). To ensure the potentialities of
tollint the thin-walled pipes and piples with a graduated diameter, the mandrel,
freely moving in rollers together with the pipe, is fixed with regard to one of the
ends of the rolling sleeve pipe, such as the flange, or it is moved periodically in
a definite plan. The n-andrel has a flange at one end, the diameter of which is
greater than the inside diameter of the sleeve but is smaller than the outside
diameter of the pipe, while the diameter of its other end is smaller than the inside'

TITLE: The Rolling of Thick-Walled Hollow Billets in Stretch-Re.duc-

PERIODICAL: Stalt, 1961, No. 2, pp. 147 - 151
TEXT: After replacing the piercing units of pilger mills by piercing
presses and stretch-reducing mills, the pilger-process became the most eco-
nomic method for mediua and large diameter tube-production. To determine
the power and other parameters nec~essary to design the old type pilger mills
and to design new equipment, the UkrNITI and the Chelyabins114 truboprokatnyy
zavod (Chelyabinsk Tube-rolling Plant) made a study of the operation of the
piercing unit of the qTn3 (CbTPZ) type pilger equipment. The conventional
tube rolling tool of the piercing unit was replaced by working and guide
rolls of new design, (Figure 1). Diameter of the working rolls: 730 mm;
diameter of the guide rolls: 440 mm; incline angle of the forming cone:

330 and 380 mm; A = 267 and 310 mm. The hollow billets processed in the
stretch-reducing mills had the following dimensions:
576 x 350 x 1600 mm
572 x 300 x 1500 mm
636 x 390 x 1500 mm.
To investigate the laws of changing wall-thickness during the rolling-out
process some billets were bored in such a wayv that their axis was displaced
in relation to the center of the machine. As a result of this billetBwere
obtained with wall-thichnesses deviating by 25%. The torsion during rolling
was determined by longitudinal grooves (15 mm wide, 10 mm. deep) made in the
billets. The metal flow was observed by fitting in holes drilled into the
billet walls 20X (2OKh) type steel screws and welding them at the contact
places on to the external surface. The metal pressure on the working roll

and mandrel rod, the torque on the engine axis were registered by several
pickups. The oscillograph indicating the torque also registered the current
intensity of the engine, and a special device indicated the rotation speed of
the rolls. The actual volocity of axial displacement of the billet was meas-
:ured by the path covered by the front part of the billet during a given time,
while the focus of deformation was filled in with metal. The tangential ve-
locity was defined by the recorded rotation number of the front and rear part
of the billet. When calculating the coefficients of tangential slip, the
theoretical speed of tangential displacement of the billet, Vt, was determin-
ed with the formula:

for billets, the wall-thickness of which varied between 17 and 25%, the wall-
thickness was reduced about 1-5-2.0 times. However, rolling billets, with a
wall-thickness not changing more than 8-10%, - showed no modification in this
respect. The main deformations of the circular screws fixed in the billet
walls took place during processing in the stretching-reducing mill in axial
direction with a simultaneous torsion in tangential direction. The peripheral
layers flow more quickly in these directions than the internal ones. This

ABSTRACT: The article describes a method for obtaining high-quality pipes from continuously~
teemed metal on pilger mills enec;rporating broaching presses in their productioa line. In
order to determine the suitability of a continuously cast blank for pipe production, a consign-
ment of squ are ingots (250 binG) was east into a 150 x 150 mm crystallizer at the Novotullskly
th th
metallurglcheskiy zavod (Novotullsk Metallurgical Plant), wi e rate of continuous teeming
varied from 1. 2 - 1.8 meters/minute. The bars were then shipped to the "Jednose" plant
(Poland) for pilger mill machining and the determination of the optimal technological para-
meters of the rolling process for pipes of different sizes, along with a study of the quality

Aof the finished product. 7be equipment used at the "Jednosell plant for the production of hot-
rolled seamless pipe from 89 to 21 mm In diameter with a wall thickness of 2.7 5 mm and
above to described in detail in the article. The equipment described operates on a, blank
in the form of square blooms, 110 -'150 mm, cut into 450 - 750 mm lengths by means of
Pelz shears. The test bars (146 X 146 mm), sorted by melt, were cut into blanks 620 mm In
length. During the process of cutting, on almost half of all the blanks, 5 - 25 mm deep end
cracks formed along the diagonal seams of the solidificatioil boundaries of the heart metal of.
the blanks. The probable causes of these cracks are discuised in the article,. and the
'changes instituted in the technological process for the pu se of eli' are
rpo minating them
described. Tbe heating temperature, for example was reduced from 128 0-1300 to 1250C.
,-~Modifications were also introduced In the extension mill. The entire lot of metal (2280
"blanks) was rolled into pipes 89 X 3.25 (4. 5) mm, which were then reduced to 60 X 3.75
t; and M X 4. 5 mm in a reduction mill for the purpose of a more thorough study of the
metal quality. The technological parameters and equillment dimensions during the rolling
process are examined in the text. 7he test indices applied In the evaluation of the quail
