Abstract

Since previous equations fail to predict M_S temperature of high carbon ferrous alloys, we first propose an equation for prediction of M_S temperature of ferrous alloys containing > 2 wt pct C. The presence of carbides (Fe₃C and Cr-rich M₇C₃) is thermodynamically considered to estimate the C concentration in austenite. Especially, equations individually specialized for lean and high Cr alloys very accurately reproduce experimental results. The chemical driving force for martensitic transformation is quantitatively analyzed based on the calculation of T₀ temperature.
