Magnesium alloys are being developed by automotive industry since their light weight helps in reducing the fuel consumption and green house gases. One of the limitations is their lower high-temperature strength and creep resistance. Therefore, newer alloys are being developed to improve this property. The latest one is based on Mg-Al-Ba-Ca system, where Ba+Ca form intermetallic compounds that improve creep resistance. However, their workability has to be optimized and microstructure and texture have to be evaluated since these are of paramount importance in deciding the ductility and workability. In view of its superior creep resistance, Mg-4Al-2Ba-2Ca is selected and its high temperature strength, hot workability, microstructure and texture is examined. While the hot working behavior will be analyzed using processing maps, microstructural and texture evolution will be studied using the Electron Back Scatter Diffraction (EBSD) technique which is very powerful for tracking these changes.
