ABSTRACT; In this studyp carried out during 1955-1958, interesting data were obtained
on the, effect of coarse- and fine-grained structure on the mechanical-properties of
stripsof ID20 alloy (6.21% Cu, 0.71% 14n, 0.11% Ti, 0.12% Fe, 0 25% Si, iraces of 1-192
bal. Al). The most coarse-grained str'u*cture was obtained by ;ressingat 380, 4202 and
450*C from a homogenized ingot and at 380 And 4201C from a nonhomogenized ingot.- A
fine structure was.obtained by pressing homogenized Ingots at 48011C and nonhomogoniz@d
ones at 450 and 4800C. The pressed'stri-os were tested for stress-rupture strength at
300 and 350* and a constant.stress of 9 W=29 and the time to failurewas determined.
The coarse-grainedstructure was found to produce a greater high-temperature strength
than the find-grained structure.. Me reduced strength of-sheets of D26 alloy..as a .orl
pared to pressed semifinished products is attributed to their fine-grained structureO.

ABSTRACT: The effect of cadmium additions on the kinetics of artificial aging of.
A1-Cu Mn and Al-Cu-Li-Cd-Mn alloy.systems has been studied. D20 and
VAD23 alloys, with and without cadmium additions, were quenched ina saltpeter
bith at 530 + 5 C and 525 4- 5 C, respective' ly,@ 165
and artificially aged, at 150,
175, 185, 200, 225 and 300 C, for 3, 5, 12, 16, 24. and 48 hours. Cadmium was found'
to inhibit the hardening of Al-Cu-Mn alloys daring artificial aging.. However
in Al-Cu__71 Mn alloys containing lithium, cadmium accelerated the process of
-irtificial aging. Orig. art. hils: I figure, I table and a bibliography of 2 referencel

ABSTRACT: Aging-induced structural changes and the kinetics of aging in aluminum-
base alloys ATsm-(4-72% zinc, 1.84% magnesium, 0.69% man6anese, 0.35% zirc'o-iium,
0...03% titanium,,and 0.5% copper) and V92 (3.34% zinc, 4.48% magnesium 0.8%nanganese,@
and 0.005% beryllium) have been studied by means of electron microscopy and x-ray
diffraction analysis. The aging kinetics were.found to be the same in both.alloys.
The decomposition of solid solution begins with the formation of Guinier Preston
zones with a high density of vacancies,.which serve as nuclei for the precipitation
of:@Ig@n2-phase and play an important part in the age hardening of the, alloys. The
templerature and duration of a ing has little or no effect on the size of Guinier
91
Prestonzones,, but a considerable eff eat on their.composition. V92 alloy age hardens
