主　　题：Electromagnetic stirring Superalloy Ingots Quality 

摘      要：The effect of electromagnetic stirring on the inner quality of K417 superalloy ingots is studied with EPMA and optical *** results show that while an electromagnetic stirring with 50Hz frequency and 80A current is imposed,the equiax crystals of K417 superalloy ingots can be effectively refined and increased,and the central shrinkage porosity and the dendritic segregation of K417 superalloy ingots are greatly reduced,so the inner quality of K417 superalloy ingots is obviously improved.
