Abstract

The possibility of atomic force microscopy application for the investigation of fatigue damage process of aluminum alloy D16AT has been substantiated. It has been shown the possibility of atomic force microscopy application for the analysis of the surface deformation relief, which is formed under cyclic loading. Deformation relief is external feature of local micro plastic deformation formed by the dislocation motion and dislocation transformation. As a result of these we can watch the extrusions, intrusions and persistent slip bands on the surface of material. Presented results of the investigation of deformation relief morphology under cyclic loading by the AFM gives the ground to suppose that the height of extrusions is grows during all stage before fatigue crack initiating. The height of extrusions rising under the cyclic loading and can be considered as a quantitative parameter of fatigue damage of structural elements made of alclad aluminum alloys.
