Abstract

Mg and Mg alloys are unsuitable for use at temperatures greater than 393 K owing to their poor creep resistance and strength at elevated temperatures. Therefore, it is essential to develop high-strength magnesium alloys for use in elevated-temperature automotive applications. Therefore phase diagrams for Mg–3Zn–2Sn–0.4Ag–xNd alloys were calculated in order to present clear guidelines for Mg alloy development. The results will help in determining solid solutions and aging treatment conditions. The effect of extruded Mg–3Zn–2Sn–0.4Ag–xNd alloys on the microstructure, texture and mechanical properties at room temperature and a high temperature of 423 K were examined.
