Abstract

Based on reviews of the corrosion-mechanical destruction of metals (in parts 1 and 2), the impact of the corrosive environment and mechanical loads on aluminum alloys is considered. The main theories and practical results of determining changes in the mechanical characteristics of aluminum alloys are presented. The values of the tensile velocity must correspond to the investigated metal-medium system and ensure that the mechanism of destruction of the tested material in the experiment on samples corresponds to the mechanism of destruction of real structures under operating conditions.
