ABSTRACT: An investigation was inade of the influence of the preparatory operations
prior to growing an the perfection of epitaxial germanium films. The perfection of
the films was inventigated as a function of the conditions for finishing the sub-
strates of Ge in hydrogen and for etching the latter in a mixture of dry hydrogen
chloride with bydr-3gen. It is found that when the substrates are treated in hydrogej
at 850c, the optimil treatment time is 40 minutes. When the substrates are pol-ished
by etching with a mixture of I.Wdrogen chloride and hydrogen, mirror-smooth films con-
taining no stacking faults are obtained. (Translation of abstract]

PERIODICAM Ogneupory, 1961, No. 1, pp. 25-31
TEXTs A study has been made of the mineralizing effect of titanium di-
oxide on compositions containing zirconium dioxide as well as magnesium
oxide and calcium oxide respectively, besides alumina. The following com-
positions were examined: with (mol %) A190 3 ~ 100; Al 203 + Zr02 = 90 + 10;
Zr02 + MgO + Al 203 ~ 33.3 : 33.3 - 33.3; Zr02 + CaO + A120 3 ~ 33-3:33.3,-33.3
with admixtures of up 4% TiO 2* In all specimens, TiO 2 improved sintering
and reduced the temperature of complete sintering from 17000C to 15000C.

composition as well as their refractoriness were determined. It is stated
that an addition of titanium dioxide greatly reduces the sintering
temperature of aluminiferous and zirconium-alumina compositions. In a
similar way, t1tanium dioxide affects the sintering of the triple equi-
molecular mixture ZrO 2 t MgO . A120 3' The specimens from 90~ Al203
+ 10% Zro 2 and ZrO21 MgO : Al 20 3 ~1 1 1 - I have a better thermal
stability than those from alumina and zirconium dioxide, which is stabiliz-
ed by magnesium oxide and calcium oxide, respectively. The coefficient of
linear thermal expansion of the equimolecular mixtures Zr02 - MgO - A190 3
and ZrO 2 "' CaO - Al 203is much smaller than that of the corresponding
mixtures without alumina. The two-component compositions A120 3 - ZrO 2 and
three-component compouitions MgO - A] 203 - ZrO2 possess high refractori.-
ness, satisfactory thermal stability, and good stability under pressure at
high temperatures. They may be used as highly refractory masses. There are
4 figures, 6 tables, and 12 references; 8 Soviet, 2 US, and 2 German.

TITLE: Decomposition of calcium zirconate in the presence of some
oxides during heating
PERIODICAL: Ogneupory, no. 12, 1961, 581 - 586
TEXT: The authors investigate the thermal resistivity of calcium
zirconate as a refractory material in the presence of the oxides of
elements of the fourth group and of alumina. For the synthesis of
calcium zirconate at 1350, 1500, and 1600 0C, they used industrial
zirconium dioxide with a content of 984, ZrO 2 and calcium carbonate, as
well as ZrO 2, T'02' S'02 , ThO., and A1203' Specimens from calcium
zirconate react at 1350 00 in contact with silica and titanium dioxide. Up
to 14500C this reaction did not take place with zirconium dioxide,
thorium dioxide, and alumina. Calcium zirconate in an equimolecular

A- , 19619 276-281
PERIODICAL: Ogneupory,Ano. 6
TEXT: The effec+ of silicon dioxide on the behavior of zirconium dioxide
during firing is investigated. Pure and commercial zirconium dioxide
were used as initial materials. Shrinkage, weight of unit volume, open
porosity and physicomechanical properties were investigated for various
mixtures, admixtures, and firing temperatures. Table 4 shows the effect
of Sio2 admixtures on the formation of the solid solution ZrO 2- MgO during
firing. The thermal expansion of samples fro'm 90 mole of ZrO 2
t 10 mole 11o' of CaO is shown graphically for various firing temperatures
and admixtures. Fig. 6 shows such curves of thermal expansion for samples
from 90 mole Vo of ZrO2 + 10 mole /"j of MgO, fired at 1,5000C, It was

established that pure zirconium dioxide sinters muc',1 worse than commercial
one. Its complete stabilization with an admixture of lQio' of 1AgO is not
even obtained during firing of up ~co 1,7000C. The admixture of siliccn
dioxide hinders stabilization of -,irconium dioxide in solid solution in
mixtures of 90 mole c,~b' of ZrO2+ 10 mole ;lo of MgO and 90 mole of ZrO2
almost the entire
10 mole of CaO. In the presence of 3-C; of S1020
magnesium oxide is bound by silicon dioxide, zirconium dioxide is not
stabilized, and the samples become flawy; in the zirconium-calcium mixture
the formation of the solid solution proceeds at lower temperature and part
of the calcium oxide is bound by zirconium dioxide. An admixture of
silicon dioxide is described as being undesirable for the prodil.etion of
highly refractory products from stabilized zirconium dioxide* and its
content must be restricted by technical requirements, The silicon-dioxide
conlent in industrial zirconium dioxide should not exceed 1%. nor 0.5~f for
the manufacture of especially important products. There are 7 figures.

ABSTRACT: Solid state reactions of La203 and Nd203 with BeO, MgO, CaO, SrO, BaO,
ZnO, and CdO were studied in 1:2 powder mixtures. Mixtures containing A1203 in the
proportion La203:RO:Al2O3 = 1:1:1 were also sintered. X-ray diffraction, thermograph.
ic, chemical phase and microscopic analyses were employed. No chemical compounds or
solid solutions were found to form on heating up to 15000 in the two-component sys-
tems except in the case of BeO. Sintering of the Ln203-HeO mixtures occurs at 1400-
-15000. When kept in air, the icamples are unstable and crumble. In the three-compo--
nent systems, no compounds are fomed up to 16500. The predominant reaction is the
formatibn of lanthanum-and neodymium aluminates; the secondary reaction is the forma-
tion of spinel-type compounds by the oxides of elements of group II.' Spinell MgAl204F-

ABSTRACT: The phase relationships in the ZrO2-Ce2O3 system were studied In a re-
ducing atmosphere.' The following characteristic s were established: formation of the
q pyrochlore-type compound Ce Zr 0
J002 -7, and three solid solutions based on zirconium
dioxide - a monoclinic (below OC), *tetragonal (above 1000C), and cubic solid solution
(from 5 to 17 mole % Ce203), stable at high temperatures; R metastable solid solution
based on Ce203 and a region of immiscibility between the indicated phases were also
found. Dflatometrio measurements established that in the concentration range from 0
to 27 mole % Ce203 there is a reversible polymorphic transformation of zirconium

ABSTRACT: For the manufacture of parts from which a high wear and
corrosion resistance is required, nitrided BI69
(4Khl4Nl4V2M) steel is used at present. However, this
steel has a number of deficiencies: a) a low depth of
nitrided layer (0.11 mm); b) lonj~ duration of the
nitriding process (60 hours, an increase to 100 hours
increases the deptli of the layer only by 0.01 mm);
c) high brittleness of the nitrided layer caused by a
sharp hardness gradient alonF, the depth of the layer;
d) tendency of shelling and e) insufficient strength of
the core. In order to find a m3re suitable type of steel
nitriding of specimens of a number of stainless steels of
standard production as well as specially prepared alloys
was carried out and their properties investigated. The
experimental results for ii;ost typical steels are given
in Tables 1 and 2 and Figures 1-0. On the basis of tl,.e
Cardl/2 results obtained replacement of steel EI6) used at present

A New Austenitic Steel for Nitriding (25Khl.8N8V2)
by steel 25Khl8E8V2 (C 0.25%, Cr 15.4%, Ni 7-5%,
W 2.2%) is recommended. The use of the proposed steel
instead of E169 has the folloi-.,ing advantages: 1) rapid
nitridin to a depth of 0.18 mm in 40 hours; 2) a stronger
core; 3~ a more uniform hardness gradient from the
surface to the core; 4) a deeper zone of positive
corrosion resistarxe and 5) absence of shelling.

Influence uf Nitriding on the Resistance to Corrosion of Stainless
Steels arrived at: 1) the change in the resistance to corrosion
of nitrided JtnelS as a function of the depth of the
ground-off layer, corresponds to the change in the
magnitude of the electrode potential. 2) The presence
was established of four zones along the depth of the
nitrided layers of stainless steels which are
characterised by specific corrosion properties and
corresponding magnit-udQs of the electrode potentials.
3) The author assumes that the layers with reduced corro-
sioh stability and reduced electrode potentials which
were detected at a certain depth of the nitrided layers
of stainless steels, consist of z:liror-ninm nitrides and ofa
solid solution which is impoveris-~_d in clarromium and
nitrogen. 4) When manufact-i-c-ing .--~ixiponents of

TITLE: Protection of Nitrided Stainless Steel Parts Against
Corrosion in Water
PERIODICAL: Metallovedeniye i termicheskaya obrabotka metallov,
1960, N1, 1, PP 10-13 (USSR)
ABSTRACT: Since the corrosion resistance of nitrided stainless
steels under the action of water is not uniform through-
out the nitrided layer, the authors divide the latter
into various zones according to corrosion resistance.
Only few data are available on the behavior of nitrided
stainless steels toward corrosion during the prucesses
of bluing, Vassivating in natrium bichromat-e (Sidney,
L., "Steel., f Nr 8, 1951) and lapping (Anderscn, K.,

Corrosional and electrochemical properties

Moscow, Oborongiz, 1962, 118-137.
TE 'XT: The primary objective of this experimental investigation is the deter-
mination of the effect of the degree of dissociation of NH3 (range: 20-8016) in the
surface layer of nitrided specimens of 4XI4H14B2M (4Khl4Nl4VZM) steel, the so-
ralled 31169 (E169) oteel, on its corrosion characteristics. 2 tables summarize
the findings. All specimens were uniformly ground down to a 0.03-mm depth for
comparative tests; grinding to different depths revealed the existence of four dif-
ferent layers: (1) An exterior zone with low corrosion resistance (CR) in water
and a relatively negative electrode potential; (Z) beginning at a 0.01-mm depth, a
zone with elevated CR in water and relatively high positive electrode potentials;
(3) beginning at deptha ranging from 0.03 to 0. 16 rnm in various steels, a zone with
low OR and low electrode -potential values; (4) the core material with an elevated
CR and relatively high positive potential. 71`&~.? technique and results of the potential

PWIODICAL: Metallovedeniye i termicheskaya obrabotka metallov,
no. 1, 1963, 23 - 25
TEXT: The effea.t of' carbon concc!ntration in the case-hardened
layer on the contact- and fatigue-strength was,investigated on
specimens carburized (for 4 h) to a depth of 1-2 mm in a. 15-litre
capacity laboratory furnace. Sintin was used as a carburizer
and the carbon content of the surface.layer was about 0.750.. if
5 drops/min were applied and about 1.3% if .20 drops/min
applied. After cooling in air, the specimens were heated in a
sait bath to 780-800 0C, oil-quenched, cooled to -70 0C and
L.empered at 150 - 170 OC. The surface was then ground-off to a
depth of 0.1 nim; the surface hardness was 61-63 HRC. The
,specimens were made to rotate between clamping rings to simulate
.the loading conditions of gear teeth; they were subjected during

rotation to contact stres'sal's varying along tLie circumference,
the maxinium being 700 I-,g,* hs well as to abo4t 21; slip. Th e
maximum contact strength,'about 3 350 Ic-i-/cm , was obtained with a
1.1~11 C content of the surThce layer. In this case, the structure
of the surface zone was acicular martensite with fine carbide
plates and grains. The fatigue strength increased almost linearly
from abov;t 66 kg/mm- for 04'60'.) C of the surface layer to about
75 kg,/m,11- for 0.9~, C and remained almost constant,with increasing
C content. Therefore, to achieve the highest fatigue and contact
strength the surface layer of case-hardened steel should be sat-
urated to contain 1 - 1.20c" C.

ABSTRACT: The authors investigated the possibility of obtaining a thin layer
with a hardness higher than Rockiiell hardness 58. For that purpose,steel Khl7N2
specimens were cyanided in a 10-liter laboratory muffle furnace into which pyro-
benzol and ammoaia were introduced. Air cooling was followed by oil quenching
from 1020 C. Finally, the specimens were treated it! -'70 C and. subsequently
te-,n?ered at -160 C. Hardness was highest after treatment at1700-750 C.* The zone
with a hardness of H.A-700 was 0.075-0.12 mm deep. 40-45 cm /min a=onia and 15
to 18 drops pyrobenzol per minute introduced into the furnace were found to
enhance hardness which reached H,-- 1040 without changing the depth of the active

ABSTRACT: EI8,6T&EI02L and ZhS6K heat-resistant alloys were calorized in a mixture
consisting of 98% ferroaluminum master al'iqr and 2% ammonium chloride at 850-1110C
for 2, 4, and 8 hr in order to determine the effect of the temperature. and duration
of expcsure on the depth of the surface la~rer wid on the structure, beat resistante,
and mechanical properties of the alloys. The weight gain per unit surface, the
calorized layer depth, and the rate of cals":.-Ang were found to increase with in-
creasing temperature of calorizing. With 1%creasing exposure time, the depth and
the weight gain of the calorized layer increased at a parabolic rate. With in-
creasing time of exposure at a constant temperature, the layer depth an~! weight gain
increaped, but the rate of calorizing decreased. The surface layer on EI867 and
ZhS6K alloys calorized at 950C for 4 hr contained .37-40% Aj__at a depth of 15 p. The
4

calor~zed layer on all alloys consisted of an outer zone with a microbardness of
700-850 and an inner, thinner zone with a microhardness of 700-600, compared with
400-350 for the base metal. Pamealing at T50C for 2 and 5 hr decreased the micro-
hardness of the outer zone from 770 to 600 and 500, respectively, but had no effect
on the hardness of the inner zone. Calorizing at 950C for 4 hr had no effect on the
tensile, rupture, and fatigue strengths and ductility characteristics of the alloys
at room and elevated temperatures, but significantly increased their oxidation re-
sistance at 1000C. The oxidation resistance of the alloys did not depend on the
temperature ard duration of calorizing. This makes it possible to calorize heat-
resistant aidkel.-base alloys at various temperatures and ',,c~ combine calorizing with
heat treatment. Orig. art. has: 4 figures. [MS]

ABSTRACT: The present study was undertaken to test the aging of vulcanized
rubber articles subject to pressure in hydraulic installations. Six vulcanized
rubbers were prepared on a 85% butadiene- and 15% 2-methyl-,5-vinylpyridine base.
:'Cy3inders (8.by 10mm) were'squeezed in e. vise at a constant 34 deformation and
lallowed to age in the air and in nitrogen for a period of 10-2C days, at tempera-
tures ranging from 100-150C. The modulrs of initial stress of the vulcanized
rubbers and the magnitude of their residual deformation were determined. It
was found that the rubbers vulcanized with thiui= as well as -with tetrachlor-
quinone vere the most resistant to aging. Unlike the usually observed relation-
sWp between the rvtes of chemical relaxet-ion and the accumulation of residual

TEXT: Construction of the bolometer is described, The
receiving semiconducting layer is 6 - 8 mm3 in area and v l0rz,thick
cockficien
Its resistance is 20 - 58 kS~ at 200C, with a temperature
of 3.5% per degree at 20 C, and a power dissipation of 200 - 300,1Lv
per de;llree. Paired blocks of the boloineter are blackened aid are
placed in an internally blackened box, covered with fluerite filters
The device is 10 van high and 11 mm in diameter and porsesses a 20 mm
tubular handle. The bolometer is com'Lected into a bridge with a
r
-u ply of 3 - 7 v. Sensitivity of the receiver is su~-,It as to allow

operation with light intensities varying from direct solar i1 'Mina-
tion to e .9. 0.0/6 of that value (from 1.1 to 0.0001 volt.cm-1).
The disadvantage of the bolometer is the nonlinearity of response
when the film is heated, and a dependence of response on the bridge
voltage. The following points are consi6ired: measurement of the
radiation balance components of leaves of vegetation, measurement
of the intensity of monochromator light beams, measurement of the
indicatrix of dispersed light, study of the radiational field of
light installations, determination of the relative emissive charac-
teristics of various bodies and the determination of the rate of
dVing of th7 ground and of leaves.
