Abstract

Dual phase steels are used in many applications for which electroplating is required. Hydrogen absorption and consequent loss of strength and ductility is therefore possible. Tensile tests and subsequent fractographic analysis of charged and uncharged specimens of a dual phase steel showed that hydrogen absorption resulted in deterioration of tensile properties. The deterioration was attributed to weakening of interfaces between ferrite and other constituents.
