The effect of crystallographic texture and deformation rate on the deformation behavior of titanium alloy VT16 after annealing at 700 – 880°C is studied. The compressive tests are performed at deformation rates 1, 10, 100, and 1000 mm/min. The stress-strain curves are plotted. The ultimate strain is determined. The microstructure of the alloy and its texture are studied using pole figures (PF) and orientation distribution functions (ODF). It is shown that the presence of an α-phase with axial texture \( \left\langle 10\overline{1}0\right\rangle \) lowers the yield strength and the flow stress of the alloy in the hardening range and the peripheral tensile stresses of the free surface of the compressed specimens, which raises the deformability of the alloy under compression. Elevation of the temperature of the specimens with growth of the deformation rate lowers the yield stress of the alloy, which also improves the deformability of the alloy under compression.

研究了晶体织构和变形速率对钛合金VT16在700-880°C退火后变形行为的影响。压缩测试以 1、10、100 和 1000 mm/min 的变形速率进行。绘制应力-应变曲线。确定最终应变。使用极图 (PF) 和取向分布函数 (ODF) 研究合金的微观结构及其织构。表明存在具有轴向纹理\( \left\langle 10\overline{1}0\right\rangle \)降低了合金在硬化范围内的屈服强度和流变应力以及压缩试样自由表面的周边拉应力，从而提高了合金在压缩下的变形能力。随着变形速率的增加试样温度的升高降低了合金的屈服应力，这也提高了合金在压缩下的变形能力。
