【摘要】 研究了微观偏析的理论模型对碳钢连铸过程中内裂纹的敏感性．模型中考虑了铁素体（δ）凝固向奥氏体（γ）凝固的转化过程，以及MnS的析出．主要讨论了钢中C，Mn，S，P对凝固过程中晶间偏析、零强度温度（ZST）、零塑性温度（ZDT）的影响．更多还原

【Abstract】 The intemal crack susceptibility of carbon steel was studied by using a micro-segregation model in which the transition of fewhic / austenitic solidification and the precipitation of MnS were considered. The effects of C, Mn, S, and P on the interdendrihc segregation, zero strength temperature(ZST), and zero ductility temperature (ZDT) of the steel were discussed.更多还原
