Alloy Phase Diagrams Study and Its Application for New Alloy Development

Abstract

  The methodology of the CALPHAD approach including construction of the thermodynamic databases is reviewed. The thermodynamic description for multicomponent systems can be predicted on the basis of the thermodynamic data evaluated in the low order systems. Some examples of alloy design, for advanced materials such as Fe, Co and Ni-based and electronic materials, are shown. It is demonstrated that the CALPHAD approach is very useful for the development of new materials, and new powerful tool for computational materials design.
