Abstract

Over thirty years ago, Dr. Kaufman pioneered the thermodynamic modeling through computational coupling of thermochemical and phase equilibrium data. This approach has not only extended the horizon of classic thermodynamics, but also created the foundation for today's system design of technologically important materials. In the present work, both aspects will be discussed in connection with magnesium alloys. As the lightest metallic structural material, magnesium has a great potential in weight-reduction of automotives. One of the significant challenges for a wider application of magnesium alloys is the low creep strength. It is well known that rate-earth alloying elements can significantly improve the creep behavior of magnesium alloys, but their high cross prevent the application in massive production of automotives. In this presentation, the effects of alkaline-earth alloy elements are explored through the computational thermodynamics approach and a new scheme for designating alloy specification is suggested. Additionally, the recent discovery of the superconductivity of the MgB2. Compound at 39K has generated a lot of interest. The aspect of the MgB2 processing is discussed through the thermodynamic modeling of the system.
