Research Abstract

The purpose of this study is to establish the laser shock processing method as a new technique for the plastic deformation process. We found that the femtosecond laser-driven shock compression forms high density of dislocations in solid materials. We suggest that the high density of dislocations is created due to the high-strain-rate plastic deformation and rapidly quenching induced by the femtosecond laser-driven shock wave.
