Crack tip strain localisation on mechanics of fracture of heat resistant steel after hydrogenation

Abstract

The fracture toughness of steel 15Kh2MFA(I{cyrillic, ukrainian}I{cyrillic, ukrainian}) after the PTL was investigated. It was established that the crack start is a multilevel process, in which the defining role is played by the turning modes of deformation. Regardless of the PTL modes in air and in the aggressive medium (electrolytic hydrogen), the resistance to brittle failure of the steel investigated increases as compared to static fracture toughness of the material in the initial state.
