在（α+β）相区对TA15钛合金棒进行锻造，研究了t_β-15℃、t_β-30℃和t_β-50℃（t_β为β相变温度）3种锻造温度对合金显微组织和抗拉强度各向异性的影响。结果表明：随着锻造温度降低，TA15钛合金中初生α_p相含量增加，片层状α相含量减少，厚度和长宽比减小，抗拉强度提高；TA15钛合金在t_β-50℃温度锻造后沿流线方向的抗拉强度可达973 MPa，3个方向抗拉强度的极差随锻造温度的降低而减小；TA15钛合金锻造后的拉伸断口均为韧性断口，锻造温度越低，初生α_p相含量越高，断口韧窝越深，而含有较多较细长片层状α相时，断口韧窝较浅。

TA15 titanium alloy bars were fored in (α+β) phase region, and the effect of three forging temperatures, namely t_β-15℃, t_β-30℃ and t_β-50℃ (t_β was β phase transition temperature), on the microstructure and tensile strength aeolotropy of the alloy was investigated. The results show that with the decrease of forging temperature, the content of primary α_p phase in the TA15 titanium alloy increased while that of lamellar α phase decreased, and the thickness and aspect ratio of lamellar α phase decreased; therefore the tensile strength increased. After forging at T_β-50℃, the tensile strength along the streamline direction of the TA15 titanium alloy reached 973 MPa. The tensile strength difference in three directions decreased with decreasing forging temperature. The tensile fracture of the forged TA15 titanium alloy was ductile fracture. The lower the forging temperature, the higher the content of primary α_p phase, the deeper the dimples on fractures; when more slender lamellar α phases existed, the fracture dimples were shallower.
