Model for the interaction between interface migration and carbon diffusion during annealing of martensite–austenite microstructures in steels

Abstract

The interaction between carbon partitioning from martensite to austenite and interface migration during annealing of martensite–austenite microstructures is modeled, assuming the same chemical potential of carbon in martensite and austenite at the interface and allowing the motion of the phase interface when a free-energy difference occurs. The simulations show that the motion of the martensite–austenite interface can be significant and can takes place in either direction.
