中文摘要:对三种铸造铝合金固溶加热保温后直接进行液氮深冷处理,并对其进行组织结构分析和力学性能测试。结果表明:固溶深冷处理较固溶处理力学性能明显提高,也比常规深冷处理性能有所改善。该工艺强化机理及工艺规范值得深入研究。
英文摘要:The microstructure and mechanical properties of three casting aluminum alloy after solution heat treatment and cryogenic treatment were studied. The results show that the mechanical properties are improved by solution cryogenic treatments. Solution-cryogenic treatments is worthy of further study.
