Abstract—

The structural state of iodide titanium after deformation by drawing at 77 K, which is the final stage of severe plastic deformation (SPD), has been analyzed and estimated in this work. The SPD has been implemented by a sequential combination of deformation techniques (compression-squirting-extrusion-drawing) that provide different stress epures. The temperature dependence of the logarithmic damping decrement of torsional oscillations in the 77–250 K temperature range has been studied to give a physical interpretation of the nonmonotonic change in the strength of the iodide titanium after SPD and to compare the calculated strength with that obtained for low purity titanium.

最终严重塑性变形阶段钛形成的结构状态分析

摘要—

在这项工作中，已经分析和评估了碘化钛在77 K拉拔变形后的结构状态，这是严重塑性变形（SPD）的最后阶段。通过顺序变形技术（压缩-挤压-挤压-拉伸）的顺序组合来实现SPD，从而提供不同的应力峰值。已经研究了在77–250 K温度范围内扭转振动的对数阻尼衰减的温度依赖性，以物理方式解释SPD后碘化钛强度的非单调变化，并将计算得出的强度与获得的强度进行比较。低纯度钛。
