摘要：

Effects of dispersion of insolvable particles on peritectic transformation kinetics in Fe-C binary alloy system have been investigated by means of a model experiment based on a diffusion couple method. During isothermal holding of the diffusion couple of delta and liquid phase samples, the peritectic transformation proceeds by migrations of ferrite(delta)/austenite(gamma) interface and liquid(L)/gamma interface. It was observed that the existence of insolvable particle, ZrO2, in delta phase retarded the migration of delta/gamma interface and also the migration of L/gamma interface. The retarding effect by the ZrO2 particles becomes strong as volume fraction of particles increases and/or particle radius decreases, which is qualitatively coincident with the effect of particles on grain growth (Zener pinning). These findings were verified by multi-phase field simulations.
