Effect of Cryogenic Cooling After Ecap on Mechanical Properties of Aluminum Alloy D16

Аннотация

Special features of the structural and mechanical behavior of aluminum alloy D16 under equal-channel angular pressing (ECAP) and subsequent cooling to cryogenic temperatures are studied. The mean grain size, the conventional yield strength, and the elongation are determined. It is shown that the ECAP refines the grains and raises the strength properties of the alloy.
