In a previous publication, a type of macro-microscopic approach is used to develop a numerical model to simulate austenite-pearlite transformation in Fe-C eutectoid steel. The primary aim was to gain some understanding about the mechanisms of pearlite growth suggested in the literature. This was achieved by modeling the eutectoid reaction kinetics based on some simple assumptions. The theories of pearlite growth are well established and to a certain extent, efforts have been made to understand the effect of alloying elements on pearlite transformation. In the present work, an attempt has been made to study the effect of Cr quantitatively on carbon diffusion in order to estimate the diffusion coefficient leading to the pearlite growth.
