Difference between alpha and delta ferrite
Web1 dag geleden · During cooling, the delta ferrite experiences a solid-state transformation to austenite, which initially forms at the gap between ferrite dendrites. The solid-state transformation continues until ferrite only remains at the former dendrites cores in the form of skeletal (also called vermicular) delta-ferrite (δ) [ 3 , 8 ].
