The effects of process atmosphere oxygen partial pressure (pO2) on the preimmersion surface structures, interfacial reactive wetting products, and mechanisms two prototype (0.15–0.20)C–(5.6–5.9)Mn–(0.4–1.9)Al–(1.1–1.5)Si–(0–0.6)Cr (wt%) third-generation advanced high-strength steels during continuous hot-dip galvanizing are determined. In this study, two-stage thermal processing routes employed...
