Project Title: Thermodynamic Modeling of Zn Containing Mg-Alloys
Project Summary: Magnesium is the lightest structural metal on earth. It is the third most abundant element dissolved in seawater and the eighth most profuse element in the Earth’s crust. The rapid growth in the world’s consumption of magnesium alloys has highlighted the need for a better understanding of a wider range of magnesium alloys with higher fatigue strength, higher creep resistance and other properties in general. Particularly at higher temperatures as magnesium is known to experiences performance challenges at elevated temperatures. As a result, there is a growing effort to develop high temperature structural magnesium alloys for weight reduction in automotive components to achieve high fuel efficiency. Calcium and zinc are two common alloying elements for magnesium alloys. Alloying magnesium with calcium and zinc is suggested to improve: the creep resistance, the strength and corrosion resistance of the alloy. Hence, establishing a magnesium database that includes calcium and zinc will help the efforts to find Mg alloys that are suitable for high temperature applications required by the transportation and aerospace industry.
In this project, I am applying computational thermodynamics approach to describe the phase equilibria of the ternary Mg-Ca-Zn system. This self consistent database will be combined with other Mg systems studied by our research group and hopefully will be helpful to understand Mg alloys and to develop new alloys with improved properties.
