Plastic deformation: a major factor in hydrogen embrittlement of low alloy steel

Hydrogen embrittlement of a low alloy steel has been studied using tensile tests and fracture mechanics techniques. Embrittlement was found to be caused by hydrogen-enhanced decohesion at internal interfaces. Hydrogen degradation of the relatively soft material requires that hydrogen is accumulated...

Description
Summary:Hydrogen embrittlement of a low alloy steel has been studied using tensile tests and fracture mechanics techniques. Embrittlement was found to be caused by hydrogen-enhanced decohesion at internal interfaces. Hydrogen degradation of the relatively soft material requires that hydrogen is accumulated on a localized scale by dislocation sweep-in.
