Bending Deformation and Surface Characteristics of 2024 Aluminum Alloy Processed by Laser-Induced Shock Wave
2024 aluminum alloy is deformed by shock waves which are induced by pulse laser of nanosecond duration. Bending deformation, residual stress and surface morphology are studied on laser-shocked specimens. It is found that laser power density and coverage rate strongly influence plastic strains and its distributions, which drive specimens to curve. The laser-shocked surfaces becomes uniform with coverage rate increasing. For specimens of thickness more than 4mm, curvature radius are proportional to specimen thickness, and the compressive residual stresses on shock surface gets more relaxed with arc height increasing.
