摘要：
The effect of non-metallic inclusions on corrosion and 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 3Al//2O//3 multiplied by (times) 2SiO//2, MnO, MnS and Al//2O//3 frequently presented blisters. Blisters appeared to be nucleated in voids produced during working of the steel. Blisters were never found in MnS inclusions.
