Abstract

Solidification paths simulated by Scheil model have been analyzed. Since the Scheil model assumes that the already solidified solid phases are “frozen,” the simulated solidification paths must follow the eutectic type paths and cross over the peritectic type boundaries to satisfy the mass balance requirement. Examples are given for comparison between the Scheil simulation results and the experimental observations for alloys in Mo-Ti-Si system.
