Abstract

âº The paper investigates mechanical surface states and surface potential modifications induced by Laser Shock Processing (LSP) on a 2050-T8 aluminum alloy. âº Local techniques (EBSD, nanoindentation, SKPFM) are used. âº Little metallurgical and work-hardening effects are obtained after LSP. âº LSP reduces inclusion-matrix surface potential gradients due to compressive surface stresses.
