摘　　要：研究了低碳钢在铸铁液中进行高温短时渗碳的动力学,并分析了渗层组织和渗碳的机制。结果表明,高温短时渗碳的渗速极快,且渗层组织中同时存在渗碳体、珠光体和铁素体。此外,还给出了渗层生长的动力学方程式。The kinetics of high-temperature and short-term Carburizing in liquid cast iron was studied. The microstructure in carburized layer and carburizing mechanism were analyzed. The results show that the rate of high-temperature and shortterm carburizing for low carbon steel will be extremely high and that cementite, pearlite and ferrite will exist simultaneously in the carburized layer. Furthermore, the kinetic equation of carburized layer growth was presented.
