英文摘要	TB9 alloy has superior strength effect through heat treatment and high corrosion resistance as metastable beta titanium alloy. The effects of solution treatment and solution followed by aging treatment on mechanical properties and microstructure of TB9 alloy were studied. The results indicate that the strength gradually decreases and the change of ductility is not obvious after solution treatment between 800 and 900 degrees C. The beta grain size quickly increases with the solution treatment above 820 degrees C. The influence of solution treatment on strength of aged TB9 alloy is not distinct between 800 and 900 degrees C, while the ductility obviously drops with the solution treatment temperature increasing, the elongation declines from 15% to 10% and the reduction in area decreases from 37.5% to below 20%. The a phase adequately precipitates and the mechanical properties are steady after solution and aging treatment (820 degrees C/30 min, WQ+520 degrees C/8 h, AC)
