【Abstract】 The Jominy end-quench curves of medium-carbon alloy steels were predicted by Yu Baihai’s nonlinear equation method. Without considering the effects of alloying elements interactions on the curves, the simulation results for multi-alloying medium-carbon steels were different from that in literature.An improved mathematic model for simulating the Jominy end-quench curves of medium-carbon alloy steels was proposed by intruducing a parameter named alloying element interactions equivalent (L e). With the improved model, the simulated Jominy curves of medium-carbon alloy steels agree very well with the experimental ones.更多还原
