Ti-8Mo-(0~9)Fe alloys were processed by mechanical alloying (MA) and subsequent spark plasma sintering (SPS) from elemental powders. The influences of preparation parameters on the performance of milled powders and sintered alloys were studied. The results show that in the Fe content range of 3 wt%~9 wt% titanium based alloys with high density and ultra-fine grain structure can be produced by SPS at 900℃ from the powders milled for 10 h. The microstructure of the titanium alloys mainly consists of β-Ti phase matrix and fcc-Ti particles, and the average grain size is in the range of 130~490 nm. It is the first time when titanium based alloys with face-centered cubic structure are produced. During the mechanical alloying process, the addition of Fe element greatly improves the glass forming ability of the alloy system, and the ability and the volume fraction of amorphous phase in the powders are obviously enhanced with increasing of Fe content. After high-energy ball-milling for 10 h, amorphous/nanocrystalline Ti-Mo-Fe composite powders exhibit favorable thermostability.
