Abstract

It is shown that within the surface layers of titanium, aluminum, lead and lead base alloy polycrystals under alternating bending there forms multilevel mesosubstructure, which governs the nucleation of surface fatigue cracks. The type of mesosubstructure and the size of structure elements are determined by the shear stability of surface layer internal structure as well as by the elastic characteristics of the substrate. The discussion is based on the theory of localized inelastic deformation waves.
