The isothermal compression dynamics of ternary Ti-6Al-4V alloy with initial martensitic structures were investigated in the high temperature range 1083–1173 K and moderate strain rate regime 0.01–10 s⁻¹. Shear banding was found to still dominate the deformation mechanism of this process, despite its nonadiabatic feature. The constitutive equation was derived with the aid of Zener–Hollomon parameter, which predicted the apparent activation energy as 534.39 kJ/mol. A combination of higher deformation temperature and lower strain rate suppressed the peak flow stress and promoted the evolution of shear bands. Both experiments and calculations demonstrated that a conspicuous temperature rise up to 83K could be induced by severe plastic deformation. This facilitated the dynamic recrystallization of deformed martensites, as evidenced by the measured microhardness profiles across shear bands.

研究了具有初始马氏体结构的三元 Ti-6Al-4V 合金在 1083-1173 K 高温范围和 0.01-10 s ^{-1中等应变率范围内的等温压缩动力学}. 尽管剪切带具有非绝热特性，但仍发现剪切带在该过程的变形机制中占主导地位。借助 Zener-Hollomon 参数推导出本构方程，预测表观活化能为 534.39 kJ/mol。较高的变形温度和较低的应变速率的结合抑制了峰值流动应力并促进了剪切带的演变。实验和计算都表明，严重的塑性变形可能会导致高达 83K 的显着温升。这促进了变形马氏体的动态再结晶，正如在剪切带上测量的显微硬度曲线所证明的那样。
