Titanium and its alloys are important metal structural materials owing to their excellent comprehensive properties, and they are widely used in various fields from military to civil industry. Low cost and good performance are two major factors which are virtually important for the development of titanium alloys. In this thesis, high O content titanium raw powders were used to prepare low-cost titanium alloy products by blended elemental powder metallurgy (P/M) process. Rare earth elements were added to incr...
