Effects of laser shock peening on fatigue performance of an ultrahigh-strength low-alloy steel fabricated via laser powder bed fusion

The present paper describes the main results from an experimental investigation into the effects of surface integrity modified via laser shock peening (LSP) on high cyclic fatigue (HCF) strength of an ultrahigh-strength low-alloy steel fabricated via laser powder bed fusion. Sets of specimens were t...
