microstructure of the glass-fiber plastics was determined microscopically. Alunino-
silicate glass-fiber plastics had a lower porosity, were less hygroscopic, and more
stabls than their alkaline analogs. A removal of absorbed water by compression molding
and hilfa temperature destroyed the microstructure of alkaline glass-fibers The flexu-
ral strength of the sties studied changed with the increasing force of compression
~from 0
.5 to 10 kg/cm It had a maximum at 3-5 kgcm2 compression. Glass-fiber plastic
jobtained in an autoclave in vacuo or tLnder pressuro had a lower porosity and higher

ABSTRACT: The possibility of separating La, nd, Er, Sm, Gd, and Yt as double
sulfates from.mmonium nitrate melts oy zone crystallization wen investigated.
Separation was Indicated after only 3 passes of the molten zone at 0 .82 cm/hr,
using ammonim sulfate as precipitant; the lanthanide double sulfates settled out
in the central portion of the bar. (Ammonium oxalate "= also effective as
precipitant.) The lighter element is more concentrated in the latter part of the
ingot; it dissolves more readily'in the NH sub 4 NO sub 3 than the heavy element
and passes to the end of the ingot. Optimum conditions for selective separation
(selection of preci-pitant, length of ingot, number of passes, lanthanide
concentration, etc.) remain to be worked out. Orig. art. has: 2 tables eund 2 fig-

Bending was done by stamps with a radius curvature of 16, 24 and 4o mm.. The im-

at 750 - 9500C for 3 hours followed by air ccoling, and tempering at 1,0000C -lo--
25'min and subsequent air cooling (for austenitic steel alloys), Metallographr
tests revealed no damage to the adhesion of 20k (20K) and Khl8Nl2M2T double-zoa-,-
ed steel during bending, despite of the separation of a carbide layer of 0.03 - 01
mm at the contact line of the primary layer and the coating. Doublecoated -t-leel
can be strained either hot or cold for stamping purposes; stamping Itself should
be performed at 1,180 - 9000C. As the zhearing and tearing strength decreases
during prolonged heating prior to stamping, this snould be curtailed as much az
possible. The permissible bending radius in hot or ~~old conditluns isj 3 - 3.5 a
(cold) for outward bending (T = 1,200 - 4000C) and 4 - 2.5 a for Anward benling.

performed at 20 - 7000C. Elongation properties were
tested on solid or welded ingots, which were cold
forged into 400 and 700 mm diameter bottoms with in-
verted plating. Only the carbon-steel layer was weld-
ed before forging with 9q2A (ECh2A) electrodes, the
coating was applied afterwards. To avoid damage of
coatings during forging the ingot*was protected with
parchment paper. The porosity of ingot and bottom

10 IM 100 #x 0 MI;r, 1 g K3Fe(CN)6 In I I of water. No porosity was found.
Rolling tests included two 400 and 700 mm shells. Coating damages were avoided
by interlayers of thin aluminum foils or strong paper. After rolling the coat-
ing was inspected as to porosity according to the described method. The authors
conclusion is: silver coated steel-sheet of 5 mm or less showed satisfactory

welded ingots. Protective interlinings of parchment paper are necessary during
pressure processing of silver-coated steel for'stampings and thin aluminum foils
and of strong paper for rolling. High surface cleanness of stamps and rollers
are essential. Silver-coated steel is not suitable for cold or hot manual stnyp-

TEXT~ The necessity for nickel economy is stressed, followed by the
description of the results of tests carried out by the NIMIMMASh on the
processibility of high-chromium Kh25T -steels by pressure. Changes of the
mechanical properties of Kh25T steel during tests at 20-1,10001. are shown
in Fig. 1. During cooling from 0 to -700^, a marked decrease of resilience
accompanied by slight improvement of tensile strength was observed.
Elongation tests at temperatures below zero were carried out in a thermo-
stat installed in a breaking machine, Cooling was achieved by sublimation
of solid carbon dioxide in ethyl alcohol. After elon-ition, bending, etc.
the processed samples were heated in order to diminish the deformation
force, The samples were subjected to repeated he-tting at temperatures of

of subse4uent thermal treatment on their mechanical properties was tested
at 760-7800C, followed by rapid water cooling., A number of samples sub-
jected to single or repeated heating up to 1,180 OC of various duration and
cooling rates were tested for tendency to intercrystallite corrosion under
the supervision of 1,G. Volikova, Tests were carried out in a copper
sulfate solution (120 hours), 65% boiling nitric acid (96 hours) and 55%
phosphoric acid 480 hours) at 70-8000, Bending tests were performed on
samples cut lengthwise and across rolled sheets at 100 - 1,1800C; the
samples were then subjected to corrosion tests according to the above
method plus soaking (2 x 48 hours) in 97% boiling acetic acid. The actual
degree of deformations was determined by marking circles of 30 mm in dia-
meter on slabs before pressing and measuring the ovals formed from these
circles after pressing. Hardness and expansion tests of various sections
of the bottoms revealed that hardness, deformation, tensile strength and

madey expansion and banding of Kh25T steel can be pax-formed without heat-
ing (at t > 150C) or with heating to 900-7000C. The heating time muet not
exceed 20 min. Under these conditions the fine-grained structure is pre-
served and satisfactory plastic properties are achieved. The bending
radius should not be less than 2,5 of the metal thickness (cold) or 1.5
(heated). Parts aubjected to bending and expansion under hot condition
should be heat-treated at 760-7800~, lor 2-3 min per mm, followed by rapid
water cooling. Kh25T steels showed no tendency to intercrystallite corro-
sion after being pressure treated either cold or heated to 900--7000C for 20
min. The high corrosion resistance of Kh25T jtceI5 in 55~, phosphoric acid
and 97% boiling acetic acid was establi3heri. After deformation procesving
(either cold or at temperatures not exceeding 90010' Kh25T ateels showed
high corrosion resistance and did not tend to intercrystallite corrosion in

TEXT: The article contains some data of the above-mentioned investigations
carried out at NIIKhIMMASh to be used in the manufacture of parts for devi-
ces of the chemical machine building industry. The investigations have been
carried out on BT1 (M) alloy sheets, 1-5 to 8 mm in thickness and on OT 4
(OT 4) sheets 1-5 and 5 mm in thickness. Fig.1 shows that the stability
( 68 and 60.2) of the alloys decreases without variation when heated up
from 20 to 7000. A maximum decrease in a temperature range of 20-4000 has

the samples only buckled due to high plasticity; in Fig.2, this is shown by
a dotted line. On investigating the mechanical properties of the VT1 tita-
nium sheets (12 and 25 mm thick) there was no indication of anisotropy of the
mechanical properties along the length and breadth of the rolling direction.
The mechanical and plastic properties of the alloys were tested under various
heat conditions. M samples were heated in the furnace (from one to three
times) up to 7500, OT4 samples up to 6000 and cooled in the air; the soaking
time was changed from 20 to 160 minutes, and the samples were cooled in dif-
ferent media (water, air and together with the furnace). The tests have
shown that triple heating with 160 minutes' soaking at temperatures below al-
l otropic conversions deteriorates only by 5-10% the'plastic properties of
both alloys. A corrosion test in a 1 516 H2SO4 solution indicated that aheat-
ing of up to 8000 with short soaking ~UP to 30 minutes) does not change the
corrosion resistance of the metal. Prolonged soaking at temperatures of 7500
deteriorates the latter property. Table 3 shows the permissible bending ra-
dii obtained from investigations with cold and hot samples., After the bend-
ing tests, corrosion tests were carried out during 100 hours under the guid-
ance of G.L. Shvarts . The technological media contained molybdenum
trisulfide, molybdenum and tungsten sulfo-

salts, as well as hydrochloric acid and sulfide compounds. The corrosion
speed of VT1 did not exceed 0-015 G/m2hour, and of the OT4 0.06 G/m2hour.
Shells rolled out from titanium sheet with a lengthwise welding seam can be
flanged with a local heating up to 300-3500, and in case the whole shell is
hot, with a general heating up to 550-7500. The largest flange diameter
is determined by the following formulas

The symbols are expl6ined in Fig. 6a. Drawing tests with titanium alloys
have been carried out in die-sets by means of a 30 ton hydraulic press.
As punch material Cq35-52 (SCh 35-52) chromium-nickel cast iron is recom-
mended; the dies should be made of the same cast iron with steel inserts or
of steel whose surfacelhas been consolidated to a hardness of RO 56-60.
The working surface of the punches and dies must have a fineness ofiv 9, and
if higher accuracy is required, the surfaces must be polished. Bottom
stamping from titanium alloys was also effected. The following conclusions
were drawn: 1. Bottom stamping from VT1 with a relative elongation of more
than 20~- can be effected in the cold state; if the press has not the neces-
sary capacity, the punches and blank should be heated to temperatures of

300-3500 or the blank should be heatpd to 550'-750 . Bottom stamping from
VTI with a relative elongation of less than 20% in the cold state is not
recommended. Bottom stamping from OT4 alloy should be carried out by
heating the die-set and the blank to temperatures of 300-3500 or by using a
hot piece with temperatures of 650-8500. 2. Die-sets for stamping ellipti-
cal bottoms should have a curvature radius of (2-3) 6* d a clearance
(unilateral) between die and punch of z = (1.05 . 1.114- 3. Cold stamping
reQuires XBA -21 (KhVL-21) or 9-32 lacquers as 1~bricante for covering the
blanks, as well as water-colloidal preparations like 6-0 (V-0) or 9-1 (V-1).
For hot stamping it is recommended to use V-0, and V-1 or dry graphite to
be sprayed on the surface. 4. The blank's edges should be avqnly-cut and
the burr removed. 5. In order to increase the plasticity and remove the re-
maining inner strainsv a heating to 550-6000 with a soaking of 3-4 minutes
per every mm of the bottom-wall thickness must be effected. 6. Corrugations
and bulges can be removed by secondary stamping or by heating them up to
400-5000 and hammering with a copper hammer on the die. Flanging, expand-
ingo flattening, bending and rolling tests with cold VT1 pipes (diameter -
26 mm, wall thickness - 1.~ mm) have been carried out. The M had a sta-
bility limit of 46.6 kG/mm and a relative elongation of 21-5%. The tests

of 26.4, 26.6, and 26.8 mm. have undergone rolling tests: no detects appea-
red on the surface and the expansion degree was 0.7-1.5% which corresponds
to the HM4-105-56 (NMKh-105-56) standard. Technological tests with 25 x

ABSTRACT: Several catalysts were tested for the condensation of
acetylene with propy"Lene at atmospheric pres2ure. Pure
catalysts without support were inactive. The following
supported catalysts were used. (1) Fe.0 + moo /SiO,.
3 3 4-
Silica gel wao impregnated wLth an aqueous solution of
ammonium molybdate. The excess solution was removed.
Silica gel was dried at 1100 and was boiled in a 5%
solution of Fe(NO 3)3-t for 10 minutes, dried and calcinated
at 5500. The catal sts 2-7 were prepared similarly. (2)

(11) TiO + WO 3/ASC, (12) WO3 + TiO/ASC were prepared
with aluminum-silicate catalyst (ASC). Beside the
above catalysts, (9) W03/S'02' (13) CaO/S '02 , and ASC
,viere also test-d. Condensation of acetylene with propylene
over above catalysts was carried out at 350-4500 forming
mostely aromatic hydrocarbons in 3.6 to 63.6% yield
(benzene, toluene, o-, m-, and p-xylenes). The forma-
tion of isoprene and piperylene was not observed. A. E.
