ABSTRACT: Direct one-step preparative methods for nethylaluminum sesquichloride,(a
mixture of Al(CH3),C1 and AlCH3Cl,) and trimethylaluminum are described. Methyl-
aluminum sesquichloride was synthesized in a sealed reactor (Popov, A. F. and K. N.
Korneyev, Author Certificate 168691. 1962, Byul. izobr, no. 5, 1965) from iodine-
activated PA-4 aluminum powder or ASD-T aluminum powder and metbyl chloride in
cyclobexane solution at a 2/3/4.65 constant initial molar ratio. The optimum prepara-
tive conditions were determined (see Table 1) to be 50-70C for 6-7 hr. The process
was tested on a previously developed continuous reactor for ethylaluminum sesquioxide
(Zhigach, A. F., A. F. Popov, and Ye. P. Bezukh Byulleten' tekhn.-ekonom. informats'
GOSINTI, v. 2, 1962, p. 39). TtLimethylaluminum was synthesized as follows: I I

IRACT: This Author Certificate introduces a method of synthesizing lithium-
rluzniaum hydride by a reaction of sodlum-aluminum hydride with lithium chloride in
die:hyl eter. To accelerate the process, it,is carried out with additions of
aluminum trialkyls. In a variant of*the synthesizing process, aluminum- trialkyls
are added in a quantity of 1-7%.

Title On the Problem of Anomalous Softening of Lead-Tin Alloys at
Room Temperature
Or1g Pub :,-DDk1. Bolgo :AN,, 1957., 10, No 1, 65-68
Abstract An investigation ims made of the change in hardness in natural
aging of lead-tin alloys containing one to 19% tin. It was
established that there exists an initial aging stage in which
the gmitur the percentagd of tin~.1he faster the increase in
hardness. By fixation of the state reached at room tempera-
ture through rapid quenching to -600C.. it was possible to
show the presence of an initial strengthening in natural agirg
even, in alloys with 15 to 19% tin. r(banks to the rapid aging
in the initial stage at room temperature, this strengthening
has previously escaped observation. An explanation is offer-
ed for the considerable discrepancy between the literature

Orig Pub DDkl. Bolg. AN., 1957.- 10, No 11 69-72
Abstract The course of the process of aging of lead-tin alloys is
divided Into four stages: 1. The latent period., character-
ized only by a slight reduction in the electric resistivity.
2. The period of spontaneous decay of the solid solution;-
characterized by a fast increase in the hardness.. a sharp
decrease in the electric resistivity,, and a change in the lat-
tice parameter in accordance with the abheme of the heterophase
decay. -3. The period of coagulation of the new phase in
the relaxation of the principal phase in the lattice, a phase
characterized by simultaneous rather weak decrease of both
the hardness and electric resistivity with the lattice para-
meter remaining constant. 4. A period of recrystallization
in softening; during this period the drop in hardness and
