Abstract
On the basis of superelement model, Cahn's transformation kinetics the ory and Scheil's additivity rule, actual gamma/alpha transformation st art temperature, A(r3) in Fe-Sigma X-i-C (X-i = Mn, Si, Ni, Mo etc.) m ulti-component low alloy steels during continuous cooling process was calculated. Influences of chemical composition, hot deformation of gam ma and cooling rate on A(r3) temperature were analyzed. Calculated A(r 3) temperatures are in reasonable agreement with measured ones.
