Titanium-based metal-metal composites show promises in many applications. In this work, iron-containing titanium-based composites were fabricated by using powder metallurgy method and rotary swaging process. Titanium-based composites with steel addition were sintered at temperature below TiFe eutectic temperature. Increase of the steel addition to 23% resulted in formation of TiFe intermetallic and density decrease in the composites. Further, the as-sintered composites present relatively good workability so hot rotary swaging of the as-sintered composites can be conducted. Steel particles were diffused into the Ti matrix and the composite transformed to a discontinuous β-Ti fiber-reinforced structure. As a result, mechanical properties (in axial direction) of the swaged composites were significantly improved. The tensile strength and elongation reached 1360 MPa and 9.3%, respectively.

钛基金属-金属复合材料在许多应用中都显示出了希望。本文采用粉末冶金法和旋锻工艺制备了含铁的钛基复合材料。在低于Ti Fe共晶温度的温度下烧结添加了钢的钛基复合材料。钢的添加量增加到23％导致形成Ti复合材料中的金属间铁和密度降低。此外，烧结后的复合材料具有相对良好的可加工性，因此可以对烧结后的复合材料进行热旋转锻造。钢颗粒扩散到Ti基体中，复合材料转变为不连续的β-Ti纤维增强结构。结果，锻造的复合材料的机械性能（沿轴向）显着提高。拉伸强度和伸长率分别达到1360MPa和9.3％。
