Preliminary Research on a New Ultra-high Strength Titanium Alloy

摘要：

　　Some research results are introduced briefly in this paper.A new kind of titanium alloy was designed based on nine elements system,which belongs to (α+β) type.Bars with diameter of 14 mm were produced via Vacuum Arc Remelting (VAR) melting and conventional forging and rolling facilities.Influence of alloy elements’ contents and heat treatments on microstructure and mechanical properties of the new alloy were studied.The results show that Ultimate Tensile Strength (UTS) is about 1200~1700MPa and Elongation (EL) is normally less than 5%at R.T.,though Electron Beam (EB) welding can be proceeded,but the toughness of the alloy is poor at R.T.High temperature (HT) short-term strength of the alloy is also acceptable up to 600℃.Based on the above performances,the new material can be applied in the corresponding circumstances.
