Superplasticity of cryogenic aluminum alloys 1201 and AMg6

The results of experimental studies aimed at the determination of the temperature-strain rate conditions under which samples of cryogenic aluminum alloys 1201 and AMg6, deformed in the creep mode at high homologous temperatures, exhibit the effect of superplasticity, as well as at studying of the structural changes which occur in the working parts of samples of these alloys during superplastic deformation are presented. The probable influence of magnesium, as the main alloying element of the AMg6 alloy, on the partial melting temperature of this alloy and on the mechanism of formation of fibrous structures during superplastic deformation of its samples at high homologous temperatures is considered.
