热处理与添加微量La、Cr对G01压铸铝合金组织和性能的影响
Heat treatment strikes aluminium alloy organization and the function effect with adding trace La , Cr to G01
本文研究了热处理工艺及添加微量La、Cr对G01压铸铝合金组织和性能的影响，通过力学性能测试、金相组织观察及SEM断口形貌观察，分析了合金热处理及添加La、Cr元素后力学性能的变化规律与金相组织的变化。结果显示：添加La、Cr后合金组织明显细化，当La的含量为0.15%，Cr的含量为0.2%时，合金的力学性能较好。合金在525℃×4h固溶处理后经过180℃×6h时效处理时，合金的综合性能达到最佳。
