Abstract
A slow strain rate tensile (SSRT) test was used to investigate the effect of laser shock peening (LSP) on stress corrosion cracking (SCC) behavior of the 304 austenitic stainless steels (ASSs) in acid chloride solution. Mechanical properties and fracture morphology evolutions of the 304 ASSs were studied as a function of the pulse energies through slow speed tensile tester and scanning electron microscopy (SEM). The results showed that the percentage elongation after fracture increased significantly as the pulse energy rose. Fractographic examination revealed that all the samples appeared a tendency to SCC in the given conditions, but specimens treated by LSP had better resistance to stress corrosion.
