Abstract

Influence of hydrogen in three different low alloy reactor pressure vessel steels with different sulphur contents, dynamic strain aging (DSA), and environmentally-assisted cracking (EAC) susceptibilities was investigated. The severity of hydrogen embrittlement was found to increase with the degree of DSA. The fracture behavior showed cleavage, quasi-cleavage and intergranular fracture along with localized shear deformed region. The underlying mechanisms were associated with plastic strain localization, nano-void nucleation and intergranular fracture.
