Manufacture and Analysis of Directional Solidification Organization of CMSX-6 Nickel-Base Superalloy

In this paper, we use the High rate solidification to study process parameters and CMSX-6 super-alloy solidification structure. And then, it can provide more basis for the industrial directionally solidified casting of superalloys blades. The results show that: under certain process parameters, it can be obtained parallel columnar crystals directional solidification structure. The organization is composed of the matrix γ phase and the secondary precipitated γ ' phase; under an optical microscope, it can be observed the shrinkage porosity due to the volumes reduction arising solidification.
