Peculiarities of operational embrittlement and fracture of structural steels under hydrogen influence

Abstract

Nowadays, degradation of long-term operated structural steels is one of the main issues facing engineering. The paper systematizes the structural, mechanical and electrochemical signs of operational degradation of structural steels, as well as the main stages of degradation: deformation aging and development of dissipated damaging in a metal bulk at nano- and micro-scale.
