The influence of various rolling methods on the mechanical properties of titanium ribbons was studied. Ribbons produced by asymmetric rolling showed 100% density and higher strength compared to ribbons produced through symmetric rolling. The temperature sensitivity of contact formation and mechanical behavior of ribbons rolled asymmetrically was determined by thermal variations in the plastic deformation mechanisms specific to titanium. In this regard, three temperature ranges were identified: low, intermediate, and high. In the low-temperature range (<100 °C), the elastic modulus and proportionality limit were significantly higher than those from symmetric rolling, although still inferior to the properties of the compact material. In the intermediate-temperature range (100–300°C), the elastic modulus and proportionality limit in the rolling direction matched those of compact titanium but were approximately three times greater than those found for samples tested transversely. In the high-temperature range (>300°C), the elastic modulus in both longitudinal and transverse directions was comparable to that of the compact material, while the proportionality limit surpassed the compact material significantly, owing to the deformation substructure observed in the ribbons. Asymmetric rolling significantly enhanced the mechanical properties of titanium ribbons compared to symmetric rolling. This enhancement was due to the shear strain component that facilitated contact formation at particle boundaries. Under optimal deformation conditions, the ribbons achieved a strength limit of ~800 MPa, comparable to the strength of ribbons produced conventionally. The plasticity of the ribbons did not exceed 1.5% because of their propensity for interparticle fracture.

研究了不同轧制方法对钛带材力学性能的影响。与通过对称轧制生产的带材相比，通过不对称轧制生产的带材具有 100% 的密度和更高的强度。接触形成的温度敏感性和不对称轧制带材的机械行为是由钛特有的塑性变形机制的热变化决定的。在这方面，确定了三个温度范围：低、中和高。在低温范围内（<100°C），弹性模量和比例极限明显高于对称轧制的弹性模量和比例极限，但仍不如致密材料的性能。在中间温度范围（100–300°C）内，轧制方向的弹性模量和比例极限与致密钛相匹配，但比横向测试样品的弹性模量和比例极限大约高出三倍。在高温范围内（>300°C），纵向和横向的弹性模量与致密材料相当，而比例极限则显着超过致密材料，这是由于在带材中观察到的变形亚结构所致。与对称轧制相比，不对称轧制显着提高了钛带的机械性能。这种增强是由于剪切应变分量促进了颗粒边界处的接触形成。在最佳变形条件下，带材达到约 800 MPa 的强度极限，与传统生产的带材强度相当。由于带材容易发生颗粒间断裂，因此其塑性不超过 1.5%。
