Abstract：
Turbine blisk with whole integral shroud can effectively improve the performance and service life of aero-engine,as a result,the investment casting technology of the turbine blisk had been paid much attention.The metallurgical defects of a turbine blisk with whole integral shroud of the investment casting process were mainly aimed at,and the investment casting process was optimized and improved with the combination of computer simulation analysis.The results show that the metallurgical defects such as misrun and porosity are effectively controlled,and the qualified rate of the product is improved.
