and AL8 alloys relined by rn'eans of BC13 exceeded ordinary parts by 1 to Z scale
grades in porosity; parts..Wilth a rough weight of 80 kg cast out of ALl alloy refined
with BC1 were equivalent in' density and mechanical p2ioperties to similar castings

cast in autoclave. The method of BC1 refining is recommended for the improve-
3
ment of castings of alloys AL4, ALIOV, AL1, and ALB and, in some instances, to
replace the casting of parts in the autoclave requiring a density of 2 to 3 on the
conventional scale. There are 2 figures and 1 table; no references.

TEXT: The paper describes the development of a method for the vacuum ~efin-
ing of Al alloys with the use of a flux, and the construction and development of a
vacuum equipment for the refining of Al alloys capLble of refining a melt of uh to
300 kg. The refining method developed was-intended to remove the various gaseous
and solid nonmetallic impurities which enter into an Al alloy in the course of its ,I
smelting and to avoid, also, the difficulties encountered with method used heretofore,
which consisted in the toxicity of the Cl and the chlorovs and fluorous salts used to
date. The basic concepts of the new method are the following: The impurities en-
countered in Al melts consist'of H and oxides, primarily Al.oxides. The H carries
a positive charge (I-11+ whereas the Al oxides are charged negatively (0?-).

Ifenc'e. the _His reiidilk~idsokb4~cl-ort-the-p'articlas of Al oxide.- If -the'H can-be-induced
by* the application of a'vacu .um to migrate to the surface of the melt, it is postulated
that the solid nonmetallic impurities should be entrained thereby and become Sus- . ~
ceptible to capture by adsorption by a suitable flux placed on the surface of the melt.
The rate of progress of such a process should be controllable simply by altering the
power applied to the vacuum pump. The investigation was made on AM (AL4) and
AA 9 (AL9) Al alloys. The relationship between the weight of a melt and the vacuum-
ing time was explored experimentally. While the test results indicated that the Mg
content remained constant regardless of the vacuuming time, the porosity of the alloy
was appreciably reduced in vacuuming tests lasting from Z to 6 minutes. The addition
of a suitable flux, as defined above, improved the degassing, with a subsequent furth6r
reduction in porosity and improvement in the mechanical properties of the alloy by
10-1514; this improvement elimir_:~tes the need for crystallization of cast parts'.in, an
autoclave in many instances. Typical -vacuum- refining times at 780-7901C, in the
presence of O.Zjo of a suitable flux, are: For a metal weight of 50-100 kg' 3 min;
100-150 kg, 5 min; 150-Z50 kg, 7-9 min. The improvements obtained by the vacuum-
-,--refi-ning--prQ(zip~uKe-with-the-adsorbing-flux-are illu'stratee by tables of mechanical

An investigation showed that beryllium and titanium, w1hen
added to the Al-SL-Mg alloy, contributed to grain refining and Increased
lalloy strength. The maximum strength of 33,5 kg/MM2 of solution-
annealed and aged alloy was attained at 0.15-0.4% Be and 0.15% Ti,
iwhile the strength.of the alloy with 0.5-1% Be without titanium vas
only - 27-29 -kg/mm2. To obtain a 50-60% outectic (for higher airtight-
noes), the content of silicon should be limited to 6*5-8*5%, Although

tent should not exceed 0*55%o Higher magnesium contents result in
