摘　　要：采用不同浇注温度和锻压力制备了铸锻复合成形6061铝合金机械外壳,并进行了室温拉伸性能和磨损性能的测试与分析。结果表明：随浇注温度从710℃提高到790℃时、锻压力从20 MPa增大到100 MPa时,机械外壳的拉伸性能和磨损性能均先提高后下降。铸锻复合成形6061铝合金机械外壳的浇注温度和锻压力优选为770℃、80 MPa。Casting-forging compound forming of 6061 aluminum alloy machine shells were prepared by different pouring temperatures and forging forces. And the room temperature tensile properties and wear resistance were tested and analyzed.The results show that both of tensile properties and wear resistance of the machine shells firstly improve and then decrease with pouring temperature increasing from 710 ℃ to 790 ℃ or forging force increasing from 20 MPa to 100 MPa. The optimized pouring temperature and forging force are 770 ℃ and 80 MPa, respectively.
