Application of Johnson-Mehl-Avrami-Kolmogorov type equation in non-isothermal phase process: Re-discussion

T0 can be given a linear relationship with transformation temperature T in relatively large parameter fluctuation ranges. The applications of non-isothermal JMAK type equation in γ→α phase process of Fe-0.002 wt%C alloy under linear cooling process and welding thermal process do show its good agreements with the experimental data.
