Abstract

The influence of the Portevin-Le Chatelier effect on the mechanical properties of AMg6 aluminum alloy specimens under static, dynamic, and cyclic loading was studied. It was found that this effect has little effect on the yield strength, tensile strength, and elongation determined under static tension at a strain rate of 5 mm/min. However, it significantly reduces impact toughness and its components-the work of crack initiation and propagation-and also reduces the number of cycles to complete failure under cyclic loading of the specimen at the same maximum cycle stress.
