Softening of Cold-Worked Al–6%Mg Alloy by Fast Heating in the 100…300 °C Temperature Range

Abstract

Kinetics of softening of cold-worked Al–6%Mg alloy is experimentally studied and analyzed as a function of time–temperature parameters of fast heating at 100…300 °C. It is shown that fast heating in this temperature range decreases the yield strength much faster than tensile strength, the intensity of softening being determined by heating temperature
