摘要
采用工艺实验研究2A12铝合金形变热处理工艺中时效温度和室温塑性变形量对材料性能的影响。结果表明:经固溶/淬火+8%室温塑性变形+(140±5)℃,15 h,及空冷人工时效工艺处理后,2A12铝合金获得良好的强塑性配合;在2A12铝合金热挤压管材旋压工艺中采用形变热处理技术,可以使旋压工件材料的综合性能得到明显提高。
The effect of aging temperature and room temperature plastic deformation ratio of thermo-mechanical treatment alloy on material performance process for 2Al2 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 2Al2 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 2Al2 aluminum alloy hot extrusion tube obviously.
