Description

For many years, aircraft and automobile industries have been seeking to improve mechanical properties in critical areas of materials. As early as 1972[l–5], people began to seek laser-shock-induced microstructure and mechanical property changes in metals. They observed that the substructures with very dense tangled dislocations were generated within the laser shock processing (LSP) area. It results in improved stress-corrosion resistance and fatigue resistance in metals. Nowadays, laser induced shocks are widely used for getting information on the behavior of materials under high dynamic pressure. Fabbro et. al. [6] denoted that over the range of laser power density of 109–1011 W/cm2, the ratio of the pressure induced by constrained way with that induced by the ablation p(τ)/pab varies from 9.6 to 3.9.

Investigation of Sound Property of Laser-Shocked Aluminum Alloy
