Abstract:Utilizing ThermoCalc,a thermodynamic computational software, and Gleeble simulation tester, chemistry design of spallingresistant wheel steels was investigated. The computational results showed that increasing Si content as well as decreasing C content is effective to reduce tread spalling since they both elevate transformation temperature of wheel steels. And Gleeble simulation test provides the evidence of improved spalling resistance by Si addition in kinetics. However, as one of the two methods to improve spalling resistance, decreasing C brings about wearresistance reduction of wheel steel while Si addition increases the strength of wheel steels remarkably with slightly reduced ductility.
