摘　　要：Al2O3颗粒弥散强化铜基复合材料因具有高强度和高导电性而在电子行业和电阻焊行业有着广阔的应用前景。Al2O3弥散强化铜基复合材料在制备过程中,由于Al2O3颗粒与铜基体的结合力较差,导致Al2O3纳米颗粒在铜基体中分散不均匀,降低复合材料的性能。本试验尝试用甘氨酸-硝酸盐法(GNP法)与高能球磨结合的方法提高Al2O3纳米颗粒与铜基体的结合力,解决Al2O3纳米颗粒在铜基体中的分散问题。The AAl2O3 particulates reinforced copper-based composites with high strength and high conductivity at ambient temperature have great potential applications in electrical industry and resistance welding industry. In the man ufacturing process of the dispersion strengthened copper-based composite, the uneven distribution of the Al2O3 nan opaticles caused by the weak combination ability between Al2O3 grains and the copper will lead to a fall of the formed composite＇s properties. This experiment was carried out in order to improve the bonding ability between Al2O3 grains and the copper by a synthetic method integrating glycine-nitrate process （GNP） with high energy roll-milling. Consequently, the solution of the distribution problem of Al2O3 nanopaticles in the copper base could be found.
