Computational Thermodynamics: Applications in Magnesium Alloy Technology

Abstract:

Truly multicomponent and multiphase materials emerged in the focus of quantitative thermodynamic descriptions using the Calphad method in recent years. A great variety of applications of such consistent Calphad-generated databases has been successfully documented in the field of Computational Thermodynamics. These comprise focused alloy development as well as materials processing, such as solidification, heat treatment and forming. Selected examples of our work in this field will be given with emphasis on applications to magnesium alloys.

The applications focus on these examples:

-- Mg-Al-Zn-Mn (AZ and AM alloy series, real solidus and liquidus)
　　-- Mg-Al-Sr-Ca-Mn (AJ, AX and AXJM advanced alloy series)
　　-- Mg-Zn-RE (ZE) alloys and Mg-RE'-RE" alloys

Microstructures of Mg-Zn-Ce (ZE) alloys support the thermodynamic calculations shown in the phase diagram section at constant 85 at.% Mg.
