Descrição: Effect of aging treatment on microstructure and mechanical properties of 55 vol%SiCp/2024 Al composite prepared by hot-isostatic pressing（HIP） process and using SiC particles with average size of 12 μm and 2024 aluminum alloy powders with average size of 19 μm, was studied. The results show that there is a compact structure and good bonding between SiC and aluminum alloy of the HIP processed SiCp/2024 Al composite. The SiCp/2024 Al composite exhibits "double-peak phenomenon" in the aging treatment process. In comparison, the maximum hardness of the aged SiCp/2024 Al composite arrives earlier than that for the 2024 Al alloy, and the main strengthening phases in the matrix are θ″ phase and S″ phase. Compared with as-sintered composite, the hardness and bending strength of the aged composite are improved from 255 HBW to 281 HBW and from 633 MPa to 747 MPa, respectively.
