AbstractThe effect of gamma' characteristic on the hydrogen embrittlement (HE) susceptibility was investigated in Fe-Ni-Cr alloys with respect to gamma' amount and antiphase boundary (APB) energy. Tensile results revealed that HE susceptibility would increase with an increase in the gamma' amount or APB energy. Fractographic analysis showed that an increase in gamma' amount enhances the frequency of intergranular cracking while the fracture mode changed from intergranular fracture to transgranular fracture with increasing APB energy. The hydrogen induced cracking mechanism is attributed to that APB energy has a greater effect on the degree of planar slip than the gamma amount. (C) 2015 Elsevier Ltd. All rights reserved.
