Beginning Time of Formation of New Phase in Fe-Zn Diffusion Couple during Non-isothermal Diffusion and Numerical Analysis for the Phase Growth Behavior.

Abstract

A numerical analysis for phase growth behavior in Fe-Zn multi-phase diffusion couple during non- isothermal diffusion has been proposed by taking formation process of a new phase into account. For the purpose, an equation which gives the beginning time of formation of new phase during the non-isothermal heating has been derived from an empirical equation which gives the beginning time during isothermal diffusion.
