dc.description.abstractWe study the structure and chemical composition of the kappa-carbide formed as a result of isothermal transformation in an Fe-3.0Mn-5.5Al-0.3C alloy using transmission electron microscopy and atom probe tomography. Both methods reveal the evolution of kappa-particle morphology as well as the partitioning of solutes. We propose that the kappa-phase is formed by a eutectoid reaction associated with nucleation growth. The nucleation of kappa-carbide is controlled by both the ordering of Al partitioned to austenite and the carbon diffusion at elevated temperatures. (C) 2012 Acta Materialia Inc.
