Abstract
Abstract—Using high-speed video recording, the stages of predestruction and development of a main crack initiated by pulsed infrared laser radiation on the surface of the AlMg6 aluminum–magnesium alloy deformed by the uniaxial tensile testing under creep conditions are studied. The role of macroscopic bands of plastic strain in the development of the last deformation jump with an amplitude of about 10%, and the generation and propagation of the main crack is revealed. A possible mechanism of fracture is discussed.
