| 中文摘要: |
| 目的 优化低镁含量ZL305铝合金热处理工艺参数。方法 采用正交试验法，研究固溶温度、固溶时间、淬火介质对低镁ZL305铝合金力学性能和组织的影响。结果 固溶温度对抗拉强度的影响最大且显著，固溶时间和淬火介质温度对抗拉强度的影响次之，但不显著；对断后伸长率影响最大的是固溶温度，其次是淬火介质温度和固溶时间，但影响均不显著。结论 当采用固溶温度为495 ℃、固溶时间为12 h、淬火介质温度为25 ℃的处理参数时，低镁ZL305铝合金材料的固溶效果最优。 |
| 英文摘要: |
| The paper aims to optimize parameters on heat treatment process of low magnesium content ZL305 aluminum alloy. The effects of solution temperature, solution time and quenching medium temperature on the mechanical properties and microstructure of low magnesium ZL305 aluminum alloy were investigated by orthogonal test. The effect of solution temperature on the tensile strength was the largest and significant. The effect of solution temperature and quenching medium on the tensile strength was the second largest, but not significant. The solution temperature had the greatest influence on the elongation after fracture, followed by the quenching medium temperature and solution time, but their impacts were not significant. The optimum solution parameters of low magnesium ZL305 aluminum alloy are: solution temperature 495 ℃, solution time 12 h, quenching medium temperature 25 ℃. |
