Powder metallurgical processing of Ti alloys has been viewed as an important means for reducing material input and fabrication costs. In this study, hydride-dehydride (HDH)Ti powder was blended with different particle sizes (0.7, 2.89, and 6.46 μm) of Mo. Ti-Mo alloy compacts were produced by a spark plasma sintering process. We investigated the effect of Mo particle sizes on microstructures and tensile properties of Ti-Mo alloys. Ti-Mo alloy with the Mo particle having a particle size of 0.7μm could be densified easily despite a low sintering temperature of 800 ﾟC. The use of small Mo particle resulted in grain growth inhibition of Ti. Furthermore, the Ti-Mo alloy sintered at 800 ﾟC exhibited the maximum tensile strength of 1296 MPa in the Ti-Mo alloys.
