為了揭示氧含量對TB8鈦合金力學性能的影響規(guī)律，通過熔煉生產(chǎn)不同氧含量的TB8鈦合金鑄錠，研究了氧含量對其軋制棒材力學性能的影響。結果表明：隨著氧含量的增加，合金相變點升高，強度增加，塑性降低。合金中平均氧含量每增加0.01%，相變點升高約2
℃，固溶+時效態(tài)抗拉強度增加約22 MPa。
In order to reveal the influence of oxygen content on the
mechanical properties of TB8 titanium alloy, TB8 titanium alloy ingot with
different oxygen contents was produced by melting, and the effect of oxygen
content on the mechanical properties of the rolled bar was studied. The result
show that when the oxygen content increases, phase transition point and strength
increase, plasticity decreases, for each additional alloy average oxygen content
of 0.01%, phase transition point increases by about 2 ℃, solid solution plus
aging tensile strength increases about 22 MPa.
