抄録	The applications of Ti and its alloys are limited to high-performance products because of expensive cost and poor plastic formability. In order to develop a cost-effective processing route for pure Ti and its alloys, pure Ti powder was used as raw material and consolidated by different power metallurgy routes in this study. Warm compaction and cold compaction were employed to consolidate Ti powder and spark plasma sintering (SPS) was used as reference method. The obtained compacts were subsequently hot extruded. The microstructure and mechanical properties of the hot-extruded pure Ti were evaluated. It was found that the samples prepared by warm compaction showed a higher tensile strength of 973.6 MPa, a better elongation of 26% and a higher hardness of 389.8 Hv comparing with the other two methods. Solid solution strengthening of oxygen was the main reinforcement mechanism for the sample prepared by warm compaction in this study. The strengthening effect of oxygen was calculated as 769.8 MPa/mass.%.
