【Abstract】 The two phase flowing model was built on the basis of the solidification characteristic of ZA27 alloy. 3D cylindrical polar coordination system was set up by means of phoenics software and finity differential thermal analysis method. The calculating result showed that it fit for the experiment result, and would simulate weightiness proportion segregation phenomena truly.更多还原
