摘　　要：通过微波烧结法制备了6061铝合金和20TiC/6061铝基复合材料,研究了烧结温度对材料组织和性能的影响。结果表明,通过微波烧结法制备的6061铝合金,随着烧结温度升高,冶金结合程度提高,组织和性能也更好。在试验烧结温度范围内,致密度最终基本稳定在96%左右;当烧结温度为560℃时,TiC/6061铝基复合材料,增强相尺寸细小且分布较均匀,基体致密、结合良好。XRD物相分析显示,6061铝合金中只有Al相存在,复合材料中只有基体相Al和增强相TiC,未生成其他相。Aluminum alloy 6061 and 20TiC/6061 aluminum matrix composites were prepared by the microwave sintering,and microstructures and properties of the two materials prepared were investigated at different sintering temperatures.The results show that with the increase of sintering temperature,metallurgical bonding ability of aluminum alloy 6061 prepared by microwave sintering is improved,and microstructure and properties of the materials are also improved at the sintering temperature range,meanwhile,the final relative density reaches approximately 96%.With sintering at 560 ℃,fine reinforcement particles with sound bonding with matrix are uniformly distributed in the 20TiC/6061 composites.XRD analysis shows that only single Al phase exists in 6061 alloy,and matrix phase Al and reinforcement TiC exist in the composites with absence of other phases.
