Preventing hydrogen embrittlement in stainless steel by means of compressive stress induced by cavitation peening

The Journal of Engineering, 2015
In this paper, it has been demonstrated that compressive residual stress induced by cavitation peening which is one of the mechanical surface modification techniques can reduce invasion of the surface of austenitic stainless steel by hydrogen. Cavitation

A novel approach to assess hydrogen embrittlement susceptibility in sheared edges of AHSS using hole expansion testing with localized cathodic charging

Journal of Materials Research and Technology
Advanced high-strength steels (AHSS) are susceptible to edge fracture and hydrogen embrittlement, particularly when both occur simultaneously. This work proposes a novel methodology for evaluating hydrogen embrittlement susceptibility at sheared edges by
