Abstract

The influence of the Portevin-Le Chatelier effect on the mechanical properties of AMg6 aluminum alloy under static, dynamic, and cyclic loading of specimens was studied. It was found that this effect has little impact on the yield strength, temporary resistance and relative elongation determined under static tension of the specimen at a strain rate of 5 mm / min. However, it significantly reduces impact toughness and its components - the energy 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 stress of the cycle.
