| 摘 要： | 通过不同的热处理制度研究了退火工艺对Ti80合金板材组织和性能的影响。结果表明,退火工艺对Ti80合金的力学性能的影响较大,在退火温度为900℃时,随着保温时间的延长,室温抗拉强度先升后降;在退火时间均为2 h的情况下,随着退火温度从850℃提高到950℃,初生α相的含量逐渐减少,β相的含量逐渐增多,初生α相的晶粒尺寸没有明显的变化。

| Abstract: | The microstructure and the mechanical properties of Ti80 alloy sheet specimens with different annealing process were studied.The results show that the effect of annealing process on the mechanical properties of Ti80 alloy is obvious.When the annealing temperature is 900 ℃,room temperature tensile strength is first increased and then decreased as the holding time.In the case of annealing time is 2 h,with the annealing temperature increased from 850 ℃ to 950 ℃,the primary α phase content is decreased and β-phase content is increased,the grain size of primary α phase do not change enormously. |
