【Abstract】 Temperature field distribution in the solidification process of ZG20Mn5V has been simulated by finite element software ANSYS.According to configuration character of the casting the most appropriate analysis method has been chosen to give attention to the precision and the time of simulation,and the simulation result of temperature field which has also been tested has been obtained.It can provide temperature field information to predict hot crack turning up of ZG20Mn5V,further,it also can lay the processing foundations for next controlling its hot crack turning up.更多还原
