Abstract

Some aspects of phase transformations controlled by carbon diffusion in Fe-C-M alloys, M being a substitutional alloying element, are discussed. The rapid carbon controlled reaction comes to an end when the carbon activity has become uniform all over the material. It is found that this state may be unstable if the alloying element M is nonuniformly distributed. A portion of the interface may then move farther into the region of untransformed material. It is proposed that the ferrite formed inside austenite grains during cooling of intercritically annealed dual-phase steels is formed by this mechanism.
