ABSTRACT% Experiments were carried out for the preparation of R4Sn compounds by
Grignard reactiont in an anhydrous hydrocarbon solvont, in the presence of ether and
tetrahydrofuran. Dialkyltin oxides can be alkylated with Grignard reagents. Because
of their basic character) the Sn compounds obtained, having a general formula of
R2R'SnOMgX, can be converted into 112RISaX with an aqueous fix solution, where X = Cl,
Br, 11 acetate, etc. R2RtSn%W can be alkylated further with a Grignard reagent to
roduce R2R2tSn. Orig. art. has: 2 formulas and 2 tables. [Orig. art. in Eng.)

TEXT: The authors investigated steel of the following chemical
composition: 0.075% C, o.6% Mn, 0.31% Sit 16.4-16.9% Cr,
7.2-7.4% Nit o.6-1.2% Alt 0.02-0.04% N2 a To establish the
relations between additional hardening and martensitic transforma-
tions after low temperatitre tempering, the authors investigated the
kinetics of hardening and the kinetics of martensite transformation
during quenching as a function of the temperature and the duration
of low temperature annealing. The kinetics of martensitic
transformation were studied on an Akulov anisometer on flat
3 x 5 x 25 mm specimens. Prior to the experiments, the specimens
were vacuum annealed for 8 hours at 1050*C and, following that,
they were subjected to intermediate treatment and etching (to a
depth of Oo2 mm on each side), The temperature was meaaured by
means of Pt/PtRh or copper constantan-thermocouples placed into the

specimen itself. Non-correspondence between the temperature of
maximum hardening and martensite formation does not depend on the
intermediate treatmentl tempering at 450 to 5000C for 3 hours has
almost no effect at all on increasing the quantity of martensite
but does cause a maximum strengthening of the steel. The temperature
of the beginning of the reversible a-+y transformation was measured
magnetometrically and was found to be 550 to 570OC- Data given in
a table show that additional hardening may occur at temperatures
which are lower than the initial temperature of the reverse trans-
formation. Therefore, additional strengthening after low tempera-
ture annealing cannot be explained by phase hardening during
reversible a-> y transformation. To elucidate the nature of this
strengthening in the steel under investigation, the authors have
studied the changes of other physical properties caused by tempering.
The results have shown that holding the metal at lower tempering
temperatures reduces the electric resistance and the volume, which
indicates that processes of rejection occur which bring about an
increase in the magnetic saturation and a change in the stability of
the residual austenite. After tempering in the temperature range

400 to 5000Cs the magnetic saturation increases to an extent which
is the greater the higher the aluminium content. To obtain confirma-
t1on that strengthening does take place during isothermal holding,
the hardness was measured during tempering; for each tempering
temperature 3 to 6 specimens were used; the testing was in vacuum
for specimens subjected to annealing at 10500C for 8 hours, quenching
from 10500C and tempering for 3 hours at 7500C. Increases in
hardness were observed which are attributed to the rejection of an
intermetallide. Chemical and X-ray analysis data of the residue
indicate that the hardening of the investigated alloys is due to
rejection of an intermetallide phase (FeNi) 3Al which is enriched
with iron and nickel. It in also necessary to consider the
possibility of a slight strengthening as a result of rejection
during tempering of martensite and of finely dispersed carbides.
Thus, the obtained results lead to the conclusion that hardening
(strengthening) of the investigated steel takes place as a result of
15 eparation of a phase which is rich in Ni, Fe and Al. There are

during coxitinuous cooling (Fig. 3). Intermediate-temperature annealing was fol-
lowed by low-timperature annealing (aging) at 5oo-6oo0c. In some cases intermedi-
ate annealirt was substituted by cold working with 2 - 40% reduction. Refr1gera-
tion treatment was not studied. Results of the investigations showed that the
effect of'intermediate-temperature annealing is determined by the annealing tempex-
ature aAd by the-aluminum content of the steel. Annealing at-700 - 7500C produces
the least stable austenite with a starting temperature of martensite tr*ansforma-
tion varying from 28 - 400C for steel containing no aluminum to 1000C for steel
with an aluminum'content of 1.12% (Fig. 4). The amount of martensite formed in
continuous.coollmg increases with increasing aluminum content. Double interiped!Bte
-temperature annealing for 2 x 1-5 h results in more martensite formed in continu-
ous cooling than does single annealing for 3 h. Double annealing also increases
ductility and corrosion resistance. Steel with 1.12% aluminum annealed twice it
7500C, for 2 x 1.5 h and~aged at 5500C contained 80% martensite and showed a ten-
sile strength of 128.kg/eq mm, yield strength of 112 kg/sq mm, 17% elongation and
44% reduction of area. Isothermal cooling after intermediate-temperature anneal-

TEXT: The authors have studied the temperature and kinetics of
the reverse martensite transformation of transition class stools
(i.9. those with austenits unstable on cooling)* the temperature
dependence of the magnetic saturation and the peculiarities of
martensite transformation on heating. The types and compositions
of steels studied are given in table 1. The reverse-transformatiau
temperature was measured with an Akulov-type magnetometer.

carried outl the temperature was then quickly brought to the next
high level. A similar procedure was used for studying the
transformation kinetics. Fig.2 shown the relative change in
magnetic saturation as a function of heating temperature for

aluminium, molybdenum and tungsten is to raise the starting
temperature of the reversetransformation (manganese and copper
somewhat reduce it), The authors therefore suggest that one way
of raising the softening temperature of transition-class
stainless steels in to raise the reverse martensite transformation
temperature by additional alloying (e.g. with molybdenum and
tungsten). The effects found were similar to those reported by
P.Bastien and A.Sulmont (Ref.2) and recall that In Fe-Ni alloys

transformation in the stools studied during heating occurs in two
stages: the first is rapid (diffusionless) and the second is slow
(diffusion). This would answer the id1ba that the martensite type-
of reverse transformation cannot occur in steels because, as a rule,
the temperature ranges for this and for aiffusion processes such an
carbide separation coincidb (Ref.10). There are 4 figures,

TITLE: Pickling of stainless steel of the transition class
PERIODICAL: Zavodskays, laboratoriya, v. 27, no. 4, 1961, 425
TEXT: The author has examined several electrolytes with a view to
rendering visible the structure of stainless steelby means of eleotro-
polishing. A similar study, but with other electrolytes, has been publish-
ed earlier by A. S. Tarantova, L. M. Pevzner, Zavodskaya laboratoriya
XXVt 9 (1959). The author achieved the beat reaults with an electrolyte
of 58% KNO 39 between 0 and 500. This temperature was maintained by the
periodic addition of liquid nitrogen to the electrolyte. The polishing
process took 10-20 sec. Furthermore, the author used 8.5 9/1 of citric
acid with 8.5 g11 of ammonium sulfate at room temperature and a current

density between 0.1 and 0.3 a/om . This electrolyte lays bare the
structure,in all stages of thermal treatment (tempering), of steAls of
the type XIMM (Khl7N7yu) as well as of several other stainless steels

of the austenite- and ferrite-austenite class. The author did not achieve
any Btable results with chromatic pickling in boiling alkaline ferrocyanide
when trying to disclose the 6-ferrite, because the pickling temperature
was too high. Conversely, hd succeeded in the electrolytic chromatic
pickling in 10. Pb(CH 3COO)2 solution at room temperature. The samples
were subjected to a slight first-pickling treatment in 1VIo oxalic acid.
Austenite as a consequence of the pickling took on a bright-blue color,
while martensite and 48-ferrite were colored dark-blue. Both a prolonga-
tion of the pickling time and a greater current density caused the forma-
tion of thicker films. In the process, austenite turned blue or straw-
yellow, while ferrite turned orange-yellow or red. (Abstracter-s note;

ABSTRACT- The authors study the effect of 0.023 and 0.052% Hf on the properties of
j5D2 steel. The steel was tubjected to mechanical tests in the hot-rolled, quenched
and annealed states. The addition Hf in the given quantities has no considerable
effect on the mechanical propertie4d microstructure, but retards austenite grain
growth noticeably at temperatures ~,11500C. Bibliography of 2 titles. I. Strebkov.

ABSTRACT: A study of thermic flux circulation through alternating-current electro-
magnet coils under stabilized operatir
g conditions, taking into account all the
sources contributing to heating (iron,, screen turn and coil resistance losses).
A novel method for calculating the maximum temperatures in coils is described and
compared with the main "clacaical" methodag and a method for the calculation of
short-circuit windings within the magnetic iron core is also suggested. This
latter method is based on experimental work carried out at the Electroaparataj
Enterprise. Orig. art. has: 10 figures and 5 tables. (Based on authors' Eng.

TITLE: Rectilinear dislocation in the plane of discontinuity of
elastic constants in an unbounded anisotropic medium

TEXT: Calculations of the stress and displacement field of a dislocation
line are based on a model which asaumea an isotropic medium# as
investigated by A. K. Head (Proc. Phys. Soo.# B66, 793, 1953)z The
dislocation line is assumed as running parallel (11zY to the plane of
discontinuity (xOz) of the elastic constants and situated near this ,
plane, with the Burgers vector oriented in an arbitrary direction. The
dislocations are in the upper semispace 1(y >O)9 and the dislocation line
is assumed to out the xOy plane at the point (0,y 0) where the stress tenaor
a0 is-acting. In this model, the stress tensor and displacement vector
