Method for preparing titanium-based composite material by recycling TC4 residual powder

The invention provides a method for preparing a titanium-based composite material by recycling TC4 residual powder, which comprises the following steps: (1) carrying out ball milling treatment on the TC4 residual powder and titanium diboride powder to obtain mixed powder; and (2) the mixed powder is subjected to vacuum hot pressing sintering treatment, and the titanium-based composite material is obtained. According to the method provided by the invention, the titanium alloy residual powder which cannot be utilized by a 3D printing technology and a powder metallurgy technology can be reused, the titanium-based composite material with excellent comprehensive performance is prepared, and meanwhile, low-cost preparation of the titanium-based composite material is realized. 本发明提供了一种TC4余粉再利用制备钛基复合材料的方法，该方法包括：(1)将TC4余粉和二硼化钛粉进行球磨处理，得到混合粉体；(2)将所述混合粉体进行真空热压烧结处理，得到所述钛基复合材料。本发明提供的方法能够再利用3D打印技术和粉末冶金技术无法利用的钛合金余粉，制备得到综合性能优异的钛基复合材料，同时实现了低成本制备钛基复合材料。
