TEXTs The authors apply the method of Induced thermoelectric moti-
ve forcep developed by Professor N.Fo Kuninp in investigating the
plastic deformation-of chips. This is based on internal changes in
the physical properties of the latter and not on the outside ph9no-
mena of plastic deformation in the metal. The changes in chip con-
traction and thermo-electric qualities of -.he deformed chip were
exami,tad in relation to the thickness of out and the rake of tool.
Plastic deformation is accompanied by work hardening which is ex-
plained by distortion of crystal matrixp produced from the transfer

mination of the thermo-electric motive force in relation to the Dla-

device on the dynamometer. A support held an indicator for precise
measurement of chip thickness. The t-z,-,)ls were made of W X-15 (ShKh-

PERIODICAL: Fizika metallov i inetallovedeniye, V.13, 1962,

Tl-'XT: According to existing views, the process of cutting
P~astic metals is based on plastic deformation of the metal
which is transformed into chip. In establishing quantitative
relations between various types of plastic deformation, two
means are available, the first is to find a flow curve for the
inetal which is the same for all types of deformation, the second
consists of establishing the equivalent specific deformation
work for various methods of deformation. In establishing equiva-
lent flow curves, it is necessary to plot a single flow curve
for vavlous types of deformation; thervby,the degree of deforma-
tion and the stress state are taken as equivalents. As a
criterion of the coincidence of flow curves for various types of
deformation, experimental results were used which are based on

purely mechanical tests of measuring the size of the metal before
and iifter deformation. In machining, the dimensions of the
deforming metal layer before and after deformation are detertained
from the deformation of the chip and, therefore, establishment of
quantitative relations between various types of deformation in the
process of cutting can be related only to this quantity, which is
an external feature and does -not determine the plastic deCormation
of the metal itself. In investigating the equivalent specific
deformation work for various methods of deformation, the method of-
induced therino e.m.f. can be applied. It was found possible to
plot a single curve of. the change in the induced thermo e.m.f.
caused by distortions in the. crystal lattice resulting from
plastic deformation as n function of the specific defornintioll
wo rk On -the assumption that the nature of internal changes i n
the metal is the same for all. types of plastic deformation, the
method of induced therino e.m.f. can also he applied in studying
the process of machining. The results are given of measurements
of the induced thermo e.m.f. of chips produced during turning 0 f
copper discs on i% thread-cutting lnthe. The chili was cut at a
speed of 8 m/min, whereby the thickness of the chili was varied

between 0.1 and 0.82 min. It was found that the dependence of
the thermo e.m.f. on the specific deformation work can be
expre-ssed by means of a single general curve for torsion, tens.'o
rolling and cutting. For all theses types of deformation,
approxiiwitely the same induced e.in.f. corresponds to equal
deformation work. The assumption that the equivalence of
deformation should be evaluated or. the basis of equivalence of
specific deformation work was confirmed by the thermo e.m.f.
method as being valid also for the case of the machining of
copper. Measurement-,; of the induced thermo e.m.f. of chip may
prove useful for finding generally valid relations inter-linking
the process of machining of metals with other well known types
of defortuattion. There are 3 figures.

ABSTRACT: The defect appeared in the form of a small crack in the
fracture of rods (Figs.1-3). A study of a large number
of longitudinal cross-sections of ingots indicated that
one of the probable causes of the defect of cold drawn
steel is the porosity of the axial part of the ingot.
In the axial zone of 2.6 ton ingots of steel SbKhl5SG a
coarse porosity reaching more than two-thirds of the
total ingot height was observed. In order to obtain a
more dense axial zone, the ingot mould was redesigned
(increased taper and increased shrinkage head, Fig.4).
With the new shape of ingot moulds the proportion of
defective heats decreased from 28.9% to 13.0%. The
use of these moulds for steel ShKh6, semis of which undergo
Card 1/1 large reduction, brought to zero the proportion of rejects
due to axial defects.

TEIT: 1. A new method was employed at the Zlatoustovskiy metallurgicheskiy
zavod (Zlatoust Metallurgical Plant) for the self-lubrication of ingot molds
during bottom pouring. Before the pouring process organic substances (petro-
latum, paraffin, stearin, eta.) were fed into the ingot mold which was gradual-
ly coated with these substances. The organic material partly bums above the
rising level of the metal and has a deoxidizing effect while at the same time
coating the walls of the Ingot mold uniformly with soot. 2. In the Zlatoust
Metallurgical Plant in cooperation with the Institut elektrosvarki im. Ye.0.
Patona (Institute of Electrowelding imeni Ye.O. Paton) a method was developed
for the purpose of keeping the slag bath which serves as a heat source in a li-
quid state during the hardening of the casting by conducting through the bath
a current (40 v, 1,500 - 1,700 a). This method resulted in the decrease of
waste products during the conversion of the castings. 3. When casting open-
hearth steel with the additic-i of silicochrome (Type 20), fumace-ferrosilicon

the checkerwork of regenerators (in the upper IV-Vlma~Lnew type of silicate
chromate brick was used /~Type 3JI- m), at the Zlatoust Metallurgical Plant. In
open-hearth furnaces at a temperature of 1,3400C of the upper cheakerwork these
bricks have to be replaaed after 250-300 castings. 5. In order to decrease the
gas-saturation of the metal when casting in basic arc furnaces, non-ferrous man-
ganese was applied during oxidation, while during the period of boiling for pre-
liminary deoxidation an iunount of about 10 kg/t pig iron and silicomanganese
(about 4 kg/t) were added,, After careful removal of the oxidizing slag the ne-
cessary amount of aluminum required for the alloy was added. The ~7efining slag
was about 2-2.5 % of the charge. The quality of the experimental casting was

TITLE: Casting flat alloy-steel ingots
PERIODICAL: Stal', no. 4, 1962, 309 - 312
MXT: Besides other defects, alloy-steel and alloy ingots of the con-
veritional square and circular section type very often have an insufficient densi-
ty, mostly in the axial zone. This is caused mainly by an increased carbon con-
tent, the presence of alloying elements, impurities in the form of high-melting
non-metallic incluaions and an-increased gas saturation of the metal. In the
bottom part of the ingot the density is usually satisfactory, due to ibe accel-
erated solidification of the metal caused by intensive cooling from the sides
and from the mold 'bottom. Evidently, the axial porosity of the.ingot can, there-!
fore, be reduced by modifying the solidification conditions of the metal accord-
ingly: by an increase of the beat extraction from the ingot bottom which inten-
sifies solidification from the bottom upward or by a more thorough heating of
the ingot bead. These conditions can be ensured partly by a change of the ingot

geometry (greater conicity, smaller height-to-average cross section ratio,
larger dead head volume) and, partly, by a more intense heating of the head.
7he most favorable conditions for obtaining a uniform, dense macrostructure are
given in the electroslag remelting process.~ At the Zlatoustovskiy metallurgi-
cbesRiy zavod (Zlittoust Metallurgical Plant) tests were carried out to cast
ingots requiring a uniform macrostructure. The test ingots were shorter, their
height-to-cross section ratio was considerably smaller (1,65) than in the con-
ventional ingots, their conicity was greater (up to 10%), which promotes crys-
tallization from the bottom upwards; the weight of the liquid metal in the head:
was greater (up to 37% of the total ingot weight). Under theseconditions the
pores forming are easily filled with liquid metal and this ensures a higher den-
stty in the axial zone of t the ingot. The shorter ingot shape, however, involves
other difficulties: larger parts must be cropped, the yield of first-grade
steel decreases, heating,.forging and rolling are more difficult. Shortened
ingots are, them-fore, cast only. in special cases (large section rods from cer-
tain steel grades and alloys). 'To obtain a uniformly dense macrostructure under
-nore favorable conditions, cooling has to be accelerated. This can only be
achieved, however, by an increase of the cooling surface in relation to the
volume-unit of the solidifying metal, in other words, by a reduction of the

test ingots were cast, with a 135-kg riser, having the following characteristics
(in bracRets the corresponding data for conventional, 43o-mm circular ingots):

C B04 X 19 H 9 (SV04KhlgNg) and C B 06 X 19 X 9 T (SV06Khl9N9T) steels was introduced.
Smelting takes place in basic electric furnaces, on carbon steel scrap,'~4ith

Chrome, nickel and-manganese are added in amounts within narrower limits than
usual (18 - 18.8%, 9.5 - 10%, 1.3 - 2% respectively); petrolatum(O-3 kg/t'on) is
used. 8) 08 X 20 H 10 r 6 (08Kh2ON1OG6) steel is smelted in basic are furnaces with

are added within narrower limits (o.o8.- o.i%, 6 - 7%, 2o- - 20.7%, 10.5 - 11%
respectively). The carbon content should not exceed 0.05% at the end of the
oxidizing period. Deoxidation takes plabe with 10 kg/ton siliconmanganese and
I kg/ton aluminum lumps, Prior to tapping ferrotitanium is added in an amount
to obtain 0.2,"o' Ti in the finished steel. 9) To increase the du*ctility of H -42
(N-42) steel during forging the smelting process was changed. In one of the
versions tested the bath was first reduced with pig iron (5 kg/ton), ferroman-
ganese (1.6 - 4.5 kg/ton) and aluminum (0-3 kg/ton), after the iron ore was
charged. In the second version, the pig iron was added with the current switched
off, a "secondary" rimming was caused, while the electrodes were immersed in the
bath for 1.5 - 12 seconds. The samples of the second version showed a higher
ductilitIy. 30 - 40 minutes after the beginning of refining.' 0.5 kg/ton aluminum
lumps and before tapping, again I kg/ton aluminum were added. The second ' version
was adopted. 10) To improve the smelting technology of the Y 7 AB WAV) and

addition of c-*-rium in the form of ferrous cerium and cerium dioxide. These
additives did not affect the macrostructure of the test steels in the cast as in
the forged condition. Raising the temperature to 1,2DOOC increased the ductility
of both grades; beyond this temperature the ductility was reduced. In the N42
gr9de the ductility decreased in proportion to the, amount of cerium. The ductility
was not affected when ferrocerium was added to them Kh2~N18 grade in an amount to
ensure a 0.05 - 0.20% ceriur6 -content, neither did the addition of cerium dioxide
with a 0.05 - 0.15% cerium content, at 1,100 - 1,1500C change the steel proper-
ties. The latter improved, however,when O.2D% Ce was added. The ductility of

ABSTRACT: The process of grass cover development started before
the Miocene epoch. Data from pollen analysis and
paleontology indicate that the herbaceous grasses
begaii to develop as early as the end of the Oligo-
cene. Highly valuable data for the acquisition of
knowledge about the ecology of herbaceous plants which
inhabited the primary steppe areas van be obtained,by
a parallel study of pollen and seed pods of the grass
family. The ecogenesis-of the fossil flora sheds light
on the climatic conditions during the emergence of
Card 1/1 herbaceous plants. . E. D. Z.

TITLE: Development of Faunas in the Black Sea Basin DurijIg
the Pliocene (0 raavitii faun Chernomorskogo bassayna

PERIODICAL: Soobshch. AN GruzSSR, 1956, Vol 17, Nr 3, pp 227-234
ABSTRACT: The article presents the sequence of succession of the
bentonic molluscan faunas in the Black Sea Basin during
the'entire Pliocene from t).1'6 Pontian to the Chauda. It
traces the development of separate forms and of some
basic groups from the Pontian to the Cimmerian, from the
Cimmerian to th.6 Kuyalnik,',from the Kuyalnik to the
Guria and from the'latter to the Chauda. The Guria and
Chauda complexes, which are considered very different
from the "Pontian" faunas, are shown to be related to
Card 1/2.

Development of Faunas (Cont.) 15-57-1-1064
the complexes of the preceeding periods. The author further notes
the zoological and geographical differences in the separate parts
of the Pliocene seas. The southeastern part, which includes the
Rion embayment, remained s ecifically unique from the Pontian through-
out the entire Pliocene. here the horizons are more closely related
to one another paleontologically than the contempory horizons in
other locations'. The existence of such direct sequence of paleon-
tological complexes difies the assumption that the Black Sea Basin
contained a sea with fauna of different origin in the periods
separating the varidus ages. Thus, the assumption that after the
Kuyalnik the entire Black Sea Basin was filled with'waters of the
Akchagyl Sea is quite erroneous. All facts point only to the
presence of an Akchagyl Sea bay in the region of the northern Black
Sqa. Statements of some investigators insisting on the existence, of
the Akchagyl in Moldavia are baseless, as is the in6istence on the
presence of the Akchagyl mactras in the Pontian of the Don River
lowlands. These 11,itactras" proved to be the common Pliocene
periwincles.
