采用粉末冶金法，通过球磨和热挤压制备了双峰尺寸非晶颗粒增强7075铝基复合材料。结果表明，金属玻璃增强体由于在过冷液相区的类液相行为而有助于提高致密化程度。金属玻璃增强体在纳米尺度和微米尺度上具有双峰尺寸分布，并且均匀地分布在基体中。在增强体/基体之间观察到一层厚度为60-80 nm的界面层，界面层的形成是元素扩散和化学反应的结果。双峰尺寸的金属玻璃颗粒的引入显着改善了力学性能，其中屈服强度和断裂强度从442和648 MPa的Al 7075增加到869和962 MPa的复合材料与17体积%的增强，分别。揭示了复合材料的强化机理。
A bimodal size metallic glassy particles reinforced 7075 aluminum composite was fabricated by powder metallurgy via ball milling and hot extrusion. The results show that metallic glassy reinforcements help to improve the densification due to the liquid-like behavior in the supercooled liquid region. The metallic glassy reinforcements were found to have a bimodal size distribution at nanoscale and microscale, and were uniformly distributed in the matrix. An interphase layer with a thickness of 60–80 nm was observed between the reinforcement/matrix resulted from elemental diffusion and chemical reaction. The introduction of bimodal size metallic glassy particles have significantly improved the mechanical properties, where the yield strength and fracture strength increase from 442 and 648 MPa for Al7075 to 869 and 962 MPa for composite with 17 vol% reinforcement, respectively. The strengthening mechanisms of the composites were revealed.
