| Abstract: | A control-grain cast processing for integral turbine wheel of superalloy using mould agitation was successfully investigated. The results show that the integral turbine wheel can be effectively produced by mould agitation. The grain size of turbine disk can reach ASTM 2-3 (0.125-0.18mm), and the shape and size of blade grains can be controlled freely. |
