研究了TC18鈦合金的室溫拉伸性能與α+β相區固溶溫度和時效溫度的關系。結果表明：在時效前，隨固溶溫度的升高，合金的強度和塑性均下降；在同一時效溫度處理后，隨固溶溫度的升高，合金的強度提高，塑性下降，同時時效強化效果提高；在同一固溶溫度處理后，隨時效溫度的升高，合金的強度下降，塑性提高。合金性能的上述變化與熱處理后組成相的參數差異有關。

The relationships between room-temperature tensile properties of TC18 titanium alloy and solution (α+β phase region) as well as aging temperatures were investigated. It is found that with the increase of the solution temperature, both the strength and plasticities decrease before aging treatment, the strengths increase and the plasticities decrease after aging at a same temperature, and the aging strengthening effect increases. After solution at a same temperature, with the increase of the aging temperature, the strengths decrease and the plasticities increase. The above changes of the properties result from the different parameters of phases after heat treatment.
