摘要： This invention concerns particulate reinforced Al-based composites, and the near net shape forming process of their components. The average size of the reinforced particle in the invented composites is 0.1–3.5 μm and the volume percentage is 10–40%, and a good interfacial bonding between the reinforced particulate and the matrix is formed with the reinforced particles uniformly distributed. The production method of its billet is to have the reinforced particles and Al-base alloy powder receive variable-speed high-energy ball-milling in the balling drum. Then, with addition of a liquid surfactant, the ball-mill proceeds to carry on ball-milling. After the ball-milling, the produced composite powder undergoes cold isostatic pressing and the subsequent vacuum sintering or vacuum hot-pressing to be shaped into a hot compressed billet, which in turn undergoes semisolid thixotropic forming and may be shaped into complex-shaped components. These components can be used in various fields. This product is featured with excellent property, good machinability, stable quality, component near net shape forming and cost effective and higher performance.
