Effect of applied potential on hydrogen embrittlement of weld simulated HSLA

Abstract

Hydrogen embrittlement behaviour of an HSLA–80 steel in the weld simulated, grain coarsened heat affected zone condition, in synthetic sea water under cathodic charging in the applied potential range of -600 to -1400 mV(SCE) has been studied using a slow strain rate technique. Loss of ductility, as reflected in the percentage elongation and percentage reduction in area values, was substantial at and beyond -800 mV(SCE). The material in the weld simulated condition showed more susceptibility than the as received material, which is considered to be a result of increased strength and a bainitic–martensitic microstructure. Fracture showed both microvoid coalescence and quasi-cleavage features and was indicative of hydrogen induced void nucleation. Both hardening and softening effects on hydrogen charging were experienced.
