Abstract

Hydrogen embrittlement (HE) in a martensitic steel has been investigated by tensile tests. It is shown that increasing hydrogen amount results in a transition of void coalescence cracking to a mixture of intergranular and quasi-cleavage cracking. In order to reveal the mechanisms of HE, a non-local ductile-brittle damage model has been proposed to model these tests. Modeling results show that HE is caused by a combined effect of HEDE, HELP and AIDS mechanisms.
