Abstract
Peritectic reaction process in iron-carbon system has been computer-simulated based on the diffusion-controlled mechanism by using the direct finite difference method to investigate the effects of the shape of δ-phase on the growth rate of γ phase. When the shape is sphere, γ phase grows the fastest, with cylinder and plate following in that order. Model experiments performed by using a solid-liquid diffusion couple method indicated that the results of the simulation are correct.
