ABSTRACT: SAP waste Is formed during the production of blanks, so that utill-zation~
of this waste Is very Important for lowering the costo The authors studied dif-
ferent methods for treating SAP waste. Pressed or rolled packs of SAP waste can
be made with minimal losses. For better results, however, the waste should be di"*
integrated. Hamer ml I Is cannot be used as they only dent the metal . The authors
found that ml I I I ng of SAP I nto shavi ngs 0. 2-0.5 mm th I ck and 1-5 mm w1 da wi th a
density of 0.3-0.5 9/cc and further disintegration in mills leads to good quality
material having a 15.2% aluminum oxide content. The further processing of waste
(stamping temperature, pressure, etc$) Is also of great Importance. increasing
the temperature, for Instance, from 450 to 580C leads to an Increase In ultimate
strength from 36 to 39 kg/sq mmg and the relative elongation Increases proportion-

ately. Higher temperatures lead to better sintering and redistribution of aluminum
oxides The best temperature for heating blanks, therefore* Is 550-580C. By fola
lowing the requirements listed In the article, secondary SAP can be produced having
the same quality as primary SAP. Orig. art# has; I figure and 5 tables.

ABSTRACT: The authors have Investigated the effect of technological conditions
especially the temperature of preliminary sintering and annealing, on the struc!
ture and mechanical properties of sintered aluminum powder products at higher
temperatures (especially above 500C). The tested material was first sintered at
temperatures of 500 and 650C for 2 hours, hot pressed at 500C under a specific
pressure of 55 kg/m2, pressed at 500-550C with 89.5% deformation, hot rolled
at 500C with 70% deformation, and cold rolled with a deformation of 50%. Pre-
liminary sintering at higher temperatures (650C) decreased the strength and hard-
ness of the semifinished product and Increased the percentage of elongation* This
effect may be due to recrystallization In microvolumes. The texture formed as a
resull of pressing and hot and cold roiling of this material was very stable up

to 650C. The mechanical properties of pressed and rolled SAP-1 material deterlora-;
ted after annealing, and micrecracks appeared. The temperature of annealing lead-'i
Ing to microcracks depends on the temperature of preliminary sintering of the
briquets. It was concluded that an Increase In the sintering temperature up to
650C markedly Increases the degastfication coefficient and consequently reduces
the tendency to microcrack formation during annealing while widening the tempera-
ture interval of the stability of the mechanical properties of the annealed and

ABSTRACT: It Is well known that aluminum powder contains numerous sources of gas,
such as the fat added during powder pulverization in ball mills, as well as moisture.
This gas Interferes with the manufacture of finished products from pressed aluminum
powder, so that Uie powder should first be heated to help eliminate the gases. The
present authors attempted to determine the optimal conditions for heating aluminum
powder by measuring the content of fat$ H2 and A120~, as well as the mechanical pro-
perties, following both cold briquetting and treatment at 100-600C. The lowest quantity
of gas was detected in powder hold at a temperature of 600C for 6 hours. The mechanical
properties of pressed blanks did not change when the powder was heated up to 600C. An

increase in temperature up to 600C, however, led to lowering of the ultimate strength
and increase In relative elongation. Formation of brickets from heated powder allows
one to obtain a monolithic high-quality product with a density of 2.6-2.7 kglsq. mm.
7bis permits elimination of additional pressing operations required during cold formatia7i
of brickets, thus lowering the load on the presses. Orig. art# has: 6 figures, 4 tables,

ABSTRACT: Up to the present time, the manufacture of pressed blanks from SAP
generally Includes the steps of cold briquetting, additional pressing or sintering
under pressure at a temperature of 450-500C, and final pressing of the blpa*. This
additional pressing of the briquet Increases the density and produces partial sintering.
Recent studies, however, have led to several innovations, such as briquetting of heated
SAP and pressing of SAP at high temperatures. The present authors therefore Investigated -
the effect of the pressing temperature on the structure and mechanical properties of the1
briquets or blanks, and the possibility of shortening the entire operation by eliminating
the additional pressing of the briquets, Studies of the microstructure, hardness and
electrical conductivity were carried out on briquets pressed at 460-600C from g~ado

briquetting temperatures, the conductivity and hardness were both decreased, and
additional pressing had little effect. The effect of pressing technology and A1203 content
on the mechanical properties is shown In the Enclosure. The authors conclude that when
briquets are made from heated powder, the briquet itself can serve as the blank, sinpe

ABSTRACT: The behavior of n 4r stress in air and in

was: zinc 4.5 and 4.3%, magnesium 1.8 and 1.5%, manganese 0.6 and 0.3%, and copper
0.75 and 0.1%. The contents of zirconium (0.17%), iron (0.32), and silicon (0.25%)
were the same In both alloys. 1~e welds were made with AMg6 and Mg4 alloy filler
wire. The specimens were stressed (below the yield strength) by bending in a special
device. It was found that the duration and temperature of aging affects the suscept
bility to delayed failure, especially in ATsM alloy welds. Specimens of this alloy
aged at 20C or at 90C were not susceptible to delayed failure, while specimens aged

at 100 (100,br) or 120 (10 hr) and 175 (1 hr),were very susceptible. The suscepti"
bility of ATsM was also affected by the filler wire. The specimens welded with
AMg6 alloy filler wire were less susceptible to delayed failure than those welded
with AMg4 alloy wire. The susceptibility of ATsMIU alloy was lower than that of ATaM
alloy and failure was observed only on the specimens welded with AMg4 filler wira and
aged at 120C for 10 hr + at 175 for I hr. Specimens of ATsM and ATsKU alloys tested-
.in argon remained intact for 50-
V0 days. Even when rem%ved from argon and left
under stress in air, no SI!S ingloccurred within 90 da 9. It appears that the delay64

failure of ATsM and ATsMU alloy welds is a result of str corrosion under the
effect of air mositure. The optimum aging conditions for both"alloys were 90C for

ABSTRACT: The kinetics of aging of an alloy of the Al-Zn-Mg system was studied at
'various temperatures immediately after quenching (30 min at 4-SOOC* cooling in water)
and after two months of aging. The alloy had the con~osition (in %)2 Zn 4.35, Mg 1.57,
14h M59 Zr 0.17t Fe 0.27, Si 0.17, Ch 0.021, bal .M - The alloy was found to be
characterized by a very long aging pariocl at 200C, probably measured in years. The 1,
set of mechanical properties and the nature of change in electrical conductivity cor-.'
respond to the zone stage of aging. Transition to phase aging may occur at a tompori-
ture as low as 50-700C; it is possible that if the holding time is increased# this -t
transition will shift toward lower temperatures. Preliminary zone aging has an appr~o-
ciable effect on subsequent aging at high temperatures. It is postulated that some 6f
the zones change in an a1lotropic manner (or in any other manner related to the zonep)
into metastable particles, and the particles thus formed have a greater thermal stabi-

aftpr using the AMg4 welding rod. For both alloys, the relative number of artificial-
ly pged samples that fractured in a period of ten years was given as function of
fr ture time. The early fractures (70 days or less) were caused byVding cracks
whi h under stress initiated fracturing. After aging 100 hr at 900C, the acks
could not propagate readily due to the higher plasticity. -Similar tests, done in an
argon Iled chamber, showed no cracking after 50-60 days even for the severest aging
conditions found in atmospheric tests. Correlations with creep studies confirued that
k corrosion cracking in alloy No. 1 can only occur for aging,at 1000C, 100 hr or at
1200C, 10 hr t 1750C, I hr. Microstructures showed that cracking generally occurred

ABSTRACT: Numerous attempts were made recently to produce oxygen-free surface com-
pounds on silicon and germanium crystals. In the first part of the present paper the authors
investigated, using eloctron diffraction analysis, the structure (in particulal/,the phase

composition) of the sulfide layer created on the surfab"'o of a'SI T_=Q_CDA~aLbrocessed in a
F th n
special sulfidation tank. The experimental resu is obtained for e lattice plane dista ces
are in good agreement with the theoretical data for SIB. The second part of the paper is
devoted to the study of the structure of germanium sulfide layers produced on the surface of
germanium monocrystals during their reaction with sulfur vapors. The Debye diagram utilim

PERIODICALs Tsvetnyye metally, 1960, No 8, pp 5~0-51
TEXT; Microscopic examination of samples of titanium sponge,
taken from various parts of a batch produced by the chloride
processq revealed that most diverse forms of crystallization of
titanium are encountered in the central zone of the reaction
chamber, where dendrites of various sizes, platelike crystals of
hexagonal habit, agglomerates of columnar crystals, and*single
crystals of irregular shape, are formed. These results,
correlated with the data on the reaction conditions, indicate that
the mode of crystallization of titanium depends on temperature and
the concentration (rate of feed) of titanium tetrachloride.
Thus, slow rates of reaction are favourable for the formation of
large, well-developed dendrites and for the uniform growth of
crystals. At increased rates of feed of titanium tetrachloride,/

in the form of thin dendrites. If the temperature is raised to
1000 OC, and the rate of feed of titanium tetrachloride slowed
downt the sponge obtained in the central zone of the reaction
vessel is granular and contains single crystals. At lower
t;.mperatures, the thickness of dendrites increases with decreasing
specific consumption of tetrachloride. In general, It can be
concluded that structure of titanium sponge depends more on the
rate of feed of titanium tetrachloride than on the reaction
temperature.

TITLE: Polymerization of Dienes Under the Influence of Homogeneous

PERIODICAL: Doklady Akademii nauk SSSR, 1960, Vol. 135, No-4, pp. 847-848
TEXT: The authors report on the considerable efficacy of homogeneous
catalysts in the production of cis-polybutadiene from butadiene in benzene
solution. The catalysts were hydrocarbon-soluble systems of cobalt chloride
(concentration 0,005 - 0-01 percentage by weight, as referred to the
monomer) in complex with pyridine or ethanol in combination with alkyl-)
dialkyl-, and trialkyl aluminum chlorides. Polymerization takes place al-
ready at OOC and 1-005 fo cobalt chloride, the polymer structure being in-
dependent of temperature. The polymer yield rises with increasing conoen-
tration of the cobalt chloride, while the molecular weight of the polymer
decreases. The polymerization rate is highest at a concentration of 0.01

whereas the molecular weight in the entire concentration range studied do-
creases simultaneous ly with the acceleration of polymerization. The tem-
perature rise from 50 to 300C also reduces the molecular weight to
1/2 - 1/3. The role of the displacement reactions becomes much more con-
siderable in the presence of lower olefins. For instance, approximatively
I V, of P-butene (referred to the monomer) considerably decelerates the
polymerization and reduces the molecular weight of the polymer from
150 000 to 90 000. On the strength of data on the microstruoture of pol'Y-
butadiene the authors found, depending on the catalyst system (Table.1%
polymerization of divinyl)f that the highest percentage of 1,4-members was
obtained with diisobutyl aluminum chloride systems (97 ~) and diethyl
aluminum chloride systems. Triieobutyl aluminum considerably increasgs the
number of 1,2-members (up to 70 %). Cobalt salts of stearic acid lead to
an only inconsiderably deviating chain :structure in the range of conoentra'-
tions ensuring a homogeneous system, Polybutadiene produced in the pre-
sence of nickel stearate has a chain structure similar to that of cobalt
stearate, but a lower molecular weight. If iron benzoate and stearate is
used, the polymerization is considerably slower than with cobalt- and

ABSTRACT: The aim of this paper is to prove that the original organo-
metallic compound is not added at once to the diene monomer
as shown by data of S.Ye.Bresler and collaborators (Ref 1).
The authorsoarriod out their experiments in pure anhydrous
argon at 250-)00 . For this purpose they used a special reaction
apparatus (Fig 1). Samplea ware taken from the reaetion veasel
within certain intervals, and by means of them the amount of
the polymer formed was determined as well as that of the lithium
ethyl which did not enter the reaction. The molar ratio between
lithium ethyl and monomer was 1/150 (with isoprene) and 1/100

styrene at +109 figure 3 the same at 240 for isoprene. These
data indicate that the addition of lithium ethyl to the monomer
proceeds gradually in the course of the entire process of poly-
merization. The polymerization of styrene and isoprene in the
presence of tetrahydrofurane with which organolithium compounds
form complexes was investigated in a similar way. Yor this
purpose, solut'8ne in he tane were used which contained 16~ of
styrene (at -20 ) or 207of isoprene (at +250). The curves
III in figures 2 and 3 show the consumption of lithium ethyl
in the course of the polymerization of styrene and isoprene,
respectively, in the presence of tetrahydrofurane (I : 5).
Curves IV show the polymer yield. They indicate the rapid
acceleration of the primary act of addition of lithium ethyl
to the monomer brought about by tetrahydrofurane. Thus, poly-
merization is also accelerated. The "living" polymer chain
thus developing remains capable of further growing during a
long time, even if the entire lithium ethyl and the monomer are
consumed. Curves V and VI (Fig 3) indicate that the polymeriza-
tion process sets in with normal rapidity when isoprene (20%)
was filled up in heptane. The data set up by the authors deal

1% by mole (referred to the monomer). A considerable dependence
of the rates of.the primary addition act and the growth of
chain on the association degree of lithium ethyl is possible.
This degree decreases with falling concentration of the
organometallic compound in solution (Ref 10). There are 3
