摘　　要：以体育器械用TC11钛合金为研究对象,研究了不同的变形温度和变形速率对合金组织与性能的影响。结果表明,随着变形温度的升高,当应变速率分别为0.010和0.001 s-1时,α相的面积分数增加;除应变速率为0.001 s-1时,在其余应变速率下,β相的动态再结晶晶粒尺寸随变形温度的升高而增大。Taking TCll titanium alloy used for sport equipment as the research object, the influences of deformation conditions on the microstructure and properties of the alloy were studied. The results show that, when alloy strain rate equals to 0.010 and 0.001 s1, the increase of the deformation temperatures can cause an increase of ct phase area fraction. Except under 0.001 s-1 strain rate, the size of β phase increase with the increase of temperatures during recrystallization process.
