摘要：
3-D velocity and temperature fields of mold filling and solidification processes of large turbine blade casting were simulated. It indicated that the velocity field of upright casting is faster and steadier than lying casting. The deformation was predicted and the rule of deformation was reflected by analyzing stress field during solidification of upright casting. The casting processes were optimized, and then applied to produce castings.
