Physical simulation of investment casting for GTD-222 Ni-based superalloy processed by controlled cooling rates

The influence of the solidification process parameters on the microstructure is still identified by the trial and error method. It is common practice to perform multiple casting tests to defecate the optimum process parameters for high-quality casting parts. In order to establish the solidification-microstructure relationship, a high-efficiency experimental method is proposed to accelerate the speed of finding the optimum casting process...
