为了揭示氧含量对TB8钛合金力学性能的影响规律，通过熔炼生产不同氧含量的TB8钛合金铸锭，研究了氧含量对其轧制棒材力学性能的影响。结果表明：随着氧含量的增加，合金相变点升高，强度增加，塑性降低。合金中平均氧含量每增加0.01%，相变点升高约2
℃，固溶+时效态抗拉强度增加约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.
