Advanced Mg alloys require a stable microstructure that maintains good mechanical properties when exposed to high temperatures. On the basis of this demand, the search for new Mg alloys has stimulated the imagination of material scientists. This review's discussion ranges from modifications of commercial Mg-Al- and Mg-Zn-based alloys by Ca and rare earth (RE) elements to the investigations of new families of Mg alloys based on Mg-Sn and Mg-Gd. It reports the fundamental findings of these efforts, including microstructure, mechanical properties, and strengthening mechanisms.
