| 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. |

| Keywords: | micro-segregation zero strength temperature zero ductility temperature internal crack |
