Study on δ-ferrite evolution and properties of laser fusion zone during post-weld heat treatment on Al-Si coated press-hardened steel

Laser welding of Al-Si coated press-hardened steel (PHS) was still a challenging due to the formation of δ-ferrite in the fusion zone. However, it was ambiguous on the δ-ferrite evolution during post-weld heat treatment (PWHT). In this study, Al-Si coated PHS was welded by laser fiber and then heat-...
