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

摘要

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.
