Abstract Without considering the effects of alloying interaction on the Jominy end��quench curves, the prediction results obtained by YU Bai��hai��s nonlinear equation method for multi��alloying steels were different from those experimental ones reported in literature. Some alloying elements have marked influence on Jominy end��quench curves of steels. An improved mathematical model for simulating the Jominy end��quench curves is proposed by introducing a parameter named alloying interactions equivalent (Le). With the improved model, the Jominy end��quench curves of steels so obtained agree very well with the experimental ones.
