Title: Reaustenitization in Fe-C steels revisited

Abstract

A finite difference method used in order to model the reaustenitization from a ferrite/cementite mixture in Fe-C steels is presented in this paper. The numerical results obtained are compared with the exact solution of the diffusion equion that describes the process for the planar geometry. The agreement between both methods is excellent in a large range of temperatures. Incidentally, the authors consider worth noting that the second moment of mass condition used by Akbay et al. [Acta Metallurgica et Materialia 47, 1649 (1994)] does not seem to be necessary in the framework of the numerical method. Finally, they compare their results with available experimental values finding good agreement.
