- 摘要:
- 通过调整熔炼过程和热处理工艺参数,研究了ZL205A铸造铝合金力学性能的变化。结果表明,铁含量对伸长率有较大影响,应控制铁含量在0.08%以下,加入1%左右晶粒细化剂能改善伸长率。固溶温度选择535～540℃,保温时间为14 h,时效温度选择152℃,保温时间为8 h较为适宜。The mechanical properties of ZL205 A alloy were investigated by adjusting smelting and heat treatment processing parameters. The results show that Fe contents influence the fracture elongation significantly and should be controlled below 0.08%. Addition of 1% grain refiner to the alloy can increase the fracture elongation. Solution treatment for 14 h at 535~540 ℃ and aging treatment for 8 h at 152 ℃ are suitable comparatively.
