A Ti-10wt.%Mg powder alloy has been produced by mechanical alloying. Elemental powders of Ti and Mg were ball milled in a Zoz-Simoloyer CM01 for 16 and 20 hours under argon. Mechanical alloying was followed by XRD, SEM and particle size analysis. Test specimens of the milled powders were produced by cold compaction and sintering (under argon). The milling resulted into a fcc TiMg solid solution for both milling durations. Sintering leads to a partial decomposition of the fcc TiMg to hcp TiMg and Ti.
