Application of Computational Thermodynamics and Calphad in Magnesium Alloy Development

  • Chapter
Proceedings of the 2nd World Congress on Integrated Computational Materials Engineering (ICME)

Abstract

This paper presents two examples of using computational thermodynamics and CALPHAD modeling in the selection and development of new magnesium alloys. The Scheil model simulation of the solidification microstructure suggests that calcium is more effective than rare earth elements (such as cerium) in suppressing the formation of Mg17Al12 phase in binary Mg-Al alloys. Calcium additions also introduce more thermally stable phases in the ternary alloys, thus improving their creep resistance and strength at elevated temperatures.
