TITLE: The synthesis of dimethylcycloeilthioxanes
PERIODICAL: Zhurnal obahchey khimii, v. 32, no. 10, 1962, 3447
TEXT: A description of the synthesis of two examples of a hitherto
unknown class of compounds: cyclosilthioxanes. The treatment of
1,3-dichlorotetramethyldisiloxane with H2S in the presence of pyri-
dine gave a crystalline compound (b. range 116-122OC/2 mm, Hg; m.p.
38-420C). From the quantitative analysis of this compound and from
ir, which showed the presence of Si-O-Si, Si-S-Si and Si-CH 3 bonds,
the structure was found to be (CH 3)2 81 0 Si(CH 3)2S Si((,H3)20 Si
7C-H T. Under similar conditions 1,5-dichloro-hexamethyltrisiloxa-
372S
ne gave a colorless, transparent liquid (b. range 120-172.50C) the
structure of which was shown to be CH 3)2 Si(CH 3)2SS'(CH 3)20.'

TITLE The An&lysis of the "Two Bic Method" for the Determination of

Publ. 8 / 1956 revi4wed 9 / 1956
In the recently published monograph by KONDRANEW the principle of the "Two
Alpha Method" was dealt with, which in characterized by the investigated
ample (insulator) being oooled (heated) in two stages with the heat transfer
:
oefficient a and a ?, From two characteristic equations two unknown thermal
constants o; t~e type. temperature conductivity a. and heat conductivity i X
ore determined. This method was not developed experimentally
similar method, the "Method of the two Balls" was used by the author for
the purpose of determining the heat constants of metals. The general part is
studied as the "Method of the two Bic" for metals and insulators. Experi-
mental results are shown in a table from which it may be seen that the
minimum ratios K - Bij/Bi2 ( on the occasion of the cooling of both balls
in a medium) are attained in the case of vortex-like regime in a free con-
0,8
vecticn and in a turbulent flow at Nu -v Re . For insulators it seems to
be beat if a compulsory flow round the samples takes place from two radii

in t .he same medium. The most favorable method for metals seems to be to
measure the characteristic number Bi 2 in a metallic melt and Bi, in some
c-ther medium ao e.g. in a malt melt, the conditions of forced conve-tion
as well as temperature being the same.

PERIODICAL: Zavodskaya Laborstoriya, 1958, Vol 24, Wr 7, pp. 872 - 874
(USSR)
ABSTRACT: As the design of heat-resistant tonsoueters involves difficult
problems the present paper describes & tensometer for measuring
the static deformations up to temperature ranges about 450'. As
with this type of tensoneter an improvement of the electrical
insulating properties of the tonsoaeter cement must be achieved,
and as on the other hand good technological properties are
required the authors used a mixture of waterglasa cement which
has a resistancet one thousand times greater than the com-
positions already known. Prom the data given may be soon that a
mixture of the composition 1 PbO + 1 Al 203 * I sio2 has the
best filler propertioal good results were obtained in the case
of electro-corundus of the TNIIASh, the softening temperature

the production of the tensometers by means of this cement -s
given. The static evaluation and the determination of the
temperature dependence of the sensitivity to tension was
aarrie4 out on a TsKTI -2 machine for creeping tests. The
tonsonoters were sounted to cylindrical standard samples of
RI 437 steel, and the measurements wort carried out within the
isothermal range. A high reproducibility of the results was
found, with the maximum errors of the deformation measurements
being about- + 3 - 5%1 this agrees with the data obtained by
means of the ';@floating extensonotor according to Martens
(Ref 3). Also a diagram of the working characteristics of the
tonsometer described is given.
There are 2 figures, 1 table, and 3 references, which are

TITLE: ~e__at-c~;~duction-rof Nickel and Nickel Alloys in Relation
to the Content of Alloying Element
veden ye, 1960, Vol 9, Nr 5,
PERIODICAL: Fizika metallov i metallo
pp 792 - 794 (USSR)
ABSTRACT: Although there is a great deal of literature on the heat
conductivity of steels and iron-based alloys. there is
not much similar data on nickel-based alloys and yet these
alloys are used at elevated temperatures. In Figures 1-3.
all the data already published on nickel alloys is
collected together in the form of curves of heat conduc-
tivity against nickel content. It can be seen from these
diagrams that, with the exception of cobalt, all the
constructed curves are similar. The addition of cobalt
slightly decreases the heat conduction, evidently because
of the similarity of cobalt and nickel atomH. Copper-nickel
alloys have increased heat conductivity. From remults on
electrolytic and commercial nickel it can be seen that the
Cardl/2 heat conductivity is strongly affected by purity. With
the addition of 3%0 impurity, the heat conductivity at room

temperature falls by a factor of 2. In the region 55-80!~
nickel, the heat conductivity is practically unaffected
by chemical composition. This leads to the conclusion t1wit
the heat conductivity of all commer--ial high-temperature
resistant nickel-based alloys is practically the same.
With increase in temperature, the dependence of heat
conductivity on nickel content levels down. There are
3 figures and 22 references. 12 of which are English.

was carried (jut in s tages of 1 - 1i liours for a total tirie 'of

the tests. the mean value of the temperature coefficient of

the relative change of electrical resistanc 9 during isothermal
annealing at a given temperature above 0300 C, the relative
change in electrical resistance at 20 C after heat treatment.
It was found that the v:,.rious )roperties measured are mostly
interrelated and the curves are of similar form for all the
Constantan wires tested. For wires with an irdtially nogative
value of a , in which the curves of a as functions of
annealing temperature twice cross the zero line, it is recoi-.U:ieii-
ded to use heat-compensating annealing .-.,ith two series of
conditions: in a region of holding at a temperature below

ABSTRACT. Factors affecting the destruction of catters of drilling bits
(CDB) were investigatEd and a number of requirements which
must be satisfied by steels of which the CDB are made were
developed Comparative impact-strengti tests were performed
on I I different types of steel It was established that the in-
c rease !n impact strergth, produ(. ed du -ing surface hardening
of the CDB by meanb of cementation, is decisively affected by
the strength of the carburized layer (CL), rather than by the
magnitude and nature of distribution of the residual and surface
stresses It is therefore essential that such alloying elements
at; Ni, Cu, etc , which tend to reduce brittleness and increase
Card 1/? the strength and plastcity of the CL be introduced into

carburized steels employed for the manufacture of the CDB. The greatest
increase in impact strength as a result of carburizalion is observed when the
ratio of the depth of the CL to the radius of the spe( men amounts to 0 IH-

TITLE: Casting proportion of low-alloyed titanium
PERIODICAL: Liteynoye proizvod.4tvo, no. 3, 1960, 2-4
TEM Investigations showed some chemical changes of titanium at tem-
peratures of 1,OOOOC causi.ng a deterioration of the mechanical properties.
New processes are being employed in the production of argon shielded arc
welded bars, pipes and various rolled goods of titanium and its alloys. In-
tricate casts, free from (.asting defects have been achieved lately. High
melting temperatures (1 725o) and a low heat conductibility (0.04 cal/cm aacl:o
affect the hardening time and fluidity of titanium. The casting properties
of titanium melted in induction furnaces, containing 0.8 - 1.c~~- carbon, have
been tested by the Chikell test (Chikel', 1. - Ref. 1: "Liteynoye proizvod-
stvoll, no. 1, 1959). The testing device consists of a 25 mm thick disk with
vertical channels I - 10 i= in diameter. The filling-up conditions of the
vertical channels are analogous to the filling up of vertical sections of

thinwalled casts. All channels more than 6 - 7 mm in diameter were filled
up to full height. At 1,8500C the vertical channels of 10 mm in diameter
fill up to the full height, 5 - 6 mm diameter channels fill up to half thoir
height. The temperature effect on the fluidity of carbon titanium is
shown in Figure 2. The best filling of forms is achieved with vacuum smelt-
ing and pouring. Figure 1~ shows tnat, the overheat being the same, the flu-
idity of titanium and steel are close. Channels of smaller diameter fill up
better with steel because of a less intensive heat transfer; wider channehs
fill up better with titanium -,han with steel due to the low heat conductivity
of titanium. The linear shrinkage of titanium is similar to that of steel;
therefore patterns for steel casting may be used for titanium casting. The
smelting method and gas content of the metal affect the quantity and location
of blowholes. Vacuum smelted titanium does not show more blowholes than
steel. At identical smelting conditions the structure of titanium casts Is
finer. Figure 4 shows dependence of primary crystals on the cross section of
castings and overheating temperature. Higher temperatures increase the grain
size. Titanium hardens fauter than steel; therefore the filling of molds
has to be accomplished faster to reduce the time of interaction of titanium

TITLEi Technological testing or hot cracks in steel castings
PERIODICAL. Litey'noye proIzvodstvo, no. 6, 1961, 7 - 9
TEXT: The technological tests generally used to determine the development
of hot cracks do not fully meet the requirements, because they principally record
the effect of the metal quality and the casting temperature within narrow limits
The technological test suggested simulates the conditions of industrial casting
adequat,i!.'y, while, moreover, the effects of various factors Involved In the cast-
ing process can be studied as well. A ring is used as test specimen which has a
cylindrical part, 100 mm In height and a conical part, 50 mm in height, and walls
of 6 and 20 mm, respectively. The Inner hollow part of the ring is formed by a
core, which ensures the required degree of shrinkage delay, actually causing the
hot cracks. The upper part with a thicker wall which Is connected to the thinner
wall of the lower part ensure the conditions necessary for thermal delay of
shrinkage and consequently for hot cracks at the bend where the thin and thick
wall sectors meet. The upper tapered part can also be made cylindrical in order

to increase the capacity of the specimen. The runner system consists of a stand
pipe and a feeder. There are two dead heads at the top of the specimen, each 25
mm In diameter. Some 15 kg of metal are fed tangentially into the cylindrical
part.. The size and shape of the runner system ensure that pouring takes a lorg V
time, so that a high temperature Is obtained In the specimen In the zone where
the metal enters. All this increases the sensitivity of the test to a number o.r
external factors affecting the crack formation. The feeder widens upward towards
the stand pipe In order to prevent solLdification. Hot cracks usually form in
the cylindrical part of the specimen andat the bend where the thick and thin wall
sectors meet. The tendency of the casting to cracking Is usually assessed by the
degree of Its crack resistance. However, the parameters Indicating this degree
do not give an Indication of the size of the cracks that form. Nor Is It suffl-
cient to assess the tendency of the casting to crack formation to the length of
the cracks. The "cracked" condition which should be applied for completing the
parumter of crack resistance takes Into account both the length and the width of
the cracks formed. Therefore, It is suggested to use the area of cracks on the
surface of the casting as quantitative parameter of Its crac)wd condition. Tests
carried out with carbon and alloyed structural steels prove the method based
on the area of cracks Is reliable. The results obtained with this method corres-

'lure were a-so studied In the laboratory of the lAningradakly polltekhnicheskly

cracks formed at the wall lAnd of carbon steel castings, most probably due to the
slight difference in the thickness of the wall sectors for the given casting con-
litIons. By changing the ratio of thickness of thin and thick wall sectors in
the specimen It is possible to determine the critical wall thicknes., which for V
given local circumstances Is necessary to prevent crack formation. As It is eaEd-
Y ti, modify ,hp vsr1cus factors of ,asting in the test suggested It is

TEM The casting properties of Ti, containing 0.8 - 1.0 % C,4&-
ted in the graphite crucible of an induction furnace, were investi-
gated. In order to determine the dependence of fluidity 'on various
factors, Chikel's probe was used; this consists of a stand and
disc with vertical channels of various diameters made in it along
it's circumference. The influence of aupe4pating temperature (dif-
-erence between casting temperature and melting p%int of Ti) and
atmosphere on the fluidity of Ti was investigated and the mechani-

died. Some aspects of the manufacture of, and defects encountered
in, T1 castings are discussed. It is concluded that the mechanical
and castirgproperties of Ti are close to those of special steel
and enable completely satisfac44ry castings of considerable comple -
xity to be obtained, in spite of some difficuities encountered.

TITLE: The effect of vacuum treatment on the casting properties of alloys
PERIODICAL: Liteynoye proizvodstvo, no. 10, 1962. 24 - 32
TEXT: The author starts with*& survey on the development of metal vacuum
treatment In the ladle and during pouring, enumerates a number of Soviet and
foreign vacuum processes and points out that vacuum treatment in the primary
ladle under slag Is the most easy to carry out, ensures a sufficiently high de-
gree of degassing and purification of the steel from non-metallic inclusions,
etc. Treatment of the metal in the ladle in a vacuum chamber takes 10 - 15 min
at a residual pressure of 5 - 15, up to 30 mm Hg, while vacuum treatment during
overflowing takes 5 - 8 min at a residual pressure under optimum conditioni of
1 - 5, often 10 - 20 mm Hg. The author gives a detailed description of instal-
lations for vacuum treatment during overflowing and In the ladle, and offers a
nwaber of graphs, figures and tables showing the test results. Both standard
mid other alloys with special physical and chemIcal properties were tested. It

was found that vacuum treatment practically does neither affect the liquidus and
solidus temperatures, nor the solidification duration of a number of alloys. al-
~pough a more protracted vacuum treatment causes such structural changes of some
alloys In the liquid state that the fluidity improves. Generally It can be said
that vacuum treatment affects the alloy fluidity in various ways. depending on
the conditions of the vacuum treatment proper and Its effect on the liquid met-
