抄録

Carbon enrichment in the austenite transformed from martensite during intercritical annealing was measured by electron probe microanalyzer and three-dimensional atom probe microscopy in Fe-2Mn-0.3C and Fe-0.35C alloys. At early stages of the transformation, negligible Mn partitioning occurs, and carbon content in austenite is higher than orthoequilibrium and paraequilibrium predictions. This is presumably attributed to finite intrinsic interface mobility and/or solute drag effect. The resultant free energy dissipation at interface was estimated.
