Abstract
Thermophysical properties (including transformation temperatures) are the critical input parameters in mathematical models of solidification and casting of metallic materials. The technique of Differential Scanning Calorimetry (DSC) was selected for the study of precipitation and phase changes in CMSX-4 alloy system. The results of the calorimetric measurements together with phase transformation temperatures determined from DSC heating and cooling curves was described. In the present paper, DSC results accompanied by scanning electron microscope characterization of CMSX-4 superalloy is applied to understand significance of precipitation or phase changes in alloy system for design heat treatment for the nickel based superalloy.
