Study of the influence of a corrosive medium on the process of damage accumulation and the nature of failure of structural aluminum alloys 1441 and V-1469 under tensile and low-cycle fatigue testing

Abstract

The kinetics of damage accumulation in the surface layers of lithium-containing structural aluminum alloys 1441 and V-1469 under tensile and fatigue tests under a rigid cycle before and after the impact of corrosive media (a salt mist test chamber and a moderately warm climate of a coastal atmosphere) was studied. The damage parameters of structural aluminum–lithium alloys and the change in the nature of their failure and in the surface relief with consideration of the combined influence of loading and a corrosive medium were evaluated.
