On the effect of non-metallic inclusions on hydrogen damage in aluminium-killed steel

Abstract

The effect of non-metallic inclusions on corrosion and on hydrogen damage in an aluminium-killed steel was studied by considering the size, shape, composition and number of inclusions. Accurate determinations of the compositions of the different inclusion compounds were performed by energy-dispersive analysis of replica-extracted particles. Clusters of alumina inclusions appear to be preferred sites for the occurrence of blisters. Complex inclusions with the phases 3Al2O3 · 2SiO2, MnO, MnS and Al2O3 frequently presented blisters. Blisters appeared to be nucleated in voids produced during working of the steel. Blisters were never found in MnS inclusions.
