摘　　要：采用原位反应法制备铝基复合材料,研究基体的合成机理,增强颗粒与基体的强化原理,铝合金热处理工艺的选择等。结果表明,当采用原位反应Al2O3颗粒增强Al-Cu基复合材料时,复合材料的晶粒可被细化。同时,采用固溶、时效处理可提高铝合金的力学性能。Adopting the method of in-situ reaction preparation of aluminum matrix composite, the synthesis mechanism of matrix, the strengthening principle of reinforcing particles and matrix, aluminum alloy heat treatment process selection, etc.were studied. The results show that using in-situ reaction Al2O3 particles reinforced Al-Cu matrix composite, the grain in the composite can be refined. The solid solution treatment and aging treatment can significantly improve the mechanical properties of Al alloy.
