Analysis of Surface Relief Evolution of Polycrystalline Aluminum Alloy Under Static Deformation.

The peculiarities of using the surface as a damage sensor of the A2024 aluminum alloy under significant plastic strains are analyzed. Physical and mechanical regularities in the spatial self-organization of the structural and mechanical defects are found, and their relationship with the pore formation and deformation processes inside the material is established. It is proved that the surface relief formation can be used as the engineering parameter of the A2024 aluminum alloy damage under static deformation. [ABSTRACT FROM AUTHOR]
