大量实验数据表明，化学成分的变换决定α+β钛合金的超塑性形变性能。在一定温度下，这种变更不仅引起α/β比例的变化，而且改变α和β相的蠕变性能。普遍使用的β稳定元素使β-Ti的示踪自扩散系数发生很大的变化。英国学者对工业板材合金IMI550 (Ti-4Mo-4Al-2Sn-0.5Si)的超
A large number of experimental data show that the chemical composition of the transformation determines the superplastic deformation properties of α + β titanium alloy. At a certain temperature, this change not only causes a change in the α / β ratio, but also changes the creep properties of the α and β phases. The commonly used β-stabilizing element causes a large change in the tracer self-diffusion coefficient of β-Ti. British scholars on the industrial plate alloy IMI550 (Ti-4Mo-4Al-2Sn-0.5Si) super
