Abstract: The effect of aging temperature and room temperature plastic deformation ratio of thermo-mechanical treatment alloy on material performance process for 2A12 aluminum alloy was investigated. The results indicate that the processing of solution/hardening+8% room temperature plastic deformation+(140±5) ℃, 15 h, air cooling artificial aging on 2A12 aluminum alloy result in a good combination match of plastic with strength. The thermo-mechanical treatment after rotary compressing increases in the overall performance of 2A12 aluminum alloy hot extrusion tube obviously.
