The Effect of Direct Strip Casting on the Kinetics of Phase Transformation of a Dual Phase Steel

Metals, 2022
A dual phase steel has been produced directly from the liquid under conditions that simulate direct strip casting and thin slab casting. The kinetics of polygonal ferrite formation during the inter-critical anneal were quantified using the JMAK approach,
