Softening of cold-worked Al - 6 % Mg alloy by fast heating in the 100...300 °C temperature range

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.
