The effect of an ultrafine-grained structure of a material on strength characteristics of an aluminum alloy under shock loads

Contemporary automotive and aerospace industry have high requirements for the reliability due to growth of the vehicle velocities. At the same time, performance of materials used for the vehicle production often operate under non-standard conditions. The paper presents a comprehensive approach to study and prediction of the behavior of materials subjected to dynamic tensile loads. Aluminum alloys Al–Mg и Al–Cu–Mg are studied in order to demonstrate possibility of the strength properties enchantment using severe plastic deformation technique. Behavior of the materials us investigated for a wide range of loading conditions.
