Nanostructure integrated laser shock peening

Graphic of Warm laser shock peening: nanostructure integrated LSP

Engineering the nanostrucutres during thermally controlled laser shock peening leads metal alloys to have both high strength/ductility, and extended fatigue life, due to ultrahigh density of precipitations, and reduced relaxation of dislocation, residual stress.
