摘　　要：研究了不同时效处理工艺对1933铝合金显微组织及室温拉伸性能的影响。结果表明：单级时效热处理时，合金的室温强度可得到显著提高，但显微组织均匀性较差，时效1（120℃，24h，空冷）是较佳的单级时效处理工艺；双级时效（110℃，12h，空冷＋180℃，6h，炉冷）时合金的微观组织比较均匀细小，虽然室温强度较低，但容易得到良好的综合性能，故双级时效为理想的时效处理工艺。合金经不同时效处理产生的组织性能变化主要与时效过程中产生的过渡沉淀强化相η＇以及GP区的体积分数等因素有关。The effect of different aging treatment technology on the microstructure and room temperature tensile properties of 1933 aluminium has been studied. The results show： after single-stage aging treatment, the room temperature strength of the alloy can be improved significantly, but the uniformity of microstrueture is worse, aging 1 （120℃, 24h, AC） is the better single-stage aging treatment technology. On the other hand, after double-stage aging （110℃, 12h, AC and 180℃, 6h, FC）, although room temperature strength is lower, but the microstructure is finer and homogeneous and good comprehensive properties may be obtained. So the ideal aging treatment technology of 1933 alloy is double-stage aging. After the different aging treating, the variation of microstructure and properties of alloy mostly is related to the volume fraction and reinforcement capability of the GP zone and the deposition reinforced phase η＇ generated in aging course.
