Al-7Si-Mg铝合金凝固过程形核模型建立及枝晶生长过程数值模拟
摘要：为开发新型耐磨合金，利用热力学计算、热分析以及组织分析等手段研究了高Mg (8w t.%~20w t.%)含量对A l-l7Si-4.5Cu-xM g合金凝固行为及组织演变的影响。结果表明：Mg含量的增加显著改变了初生Mg2Si的形貌以及凝固行为。ThennoCalc模拟预测合金凝固过 程中有6个反应，即形成初生M g2S i;两个二元...

Precipitation-hardened aluminium alloys typically obtain their strength by forming second-phase particles, which, however, often have a negative effect on formability. To enable both lightweight construction and forming of complex parts such as body panels, high strength and formability are required simu...

The phase angle diagram was similar to the results of HT 375–5 until 500 h of exposure to salt spray. However, the modulus impedance gradually decreased, and the phase angle peak value also decreased after 1000 h of exposure to salt spray. Furthermore, after 2000 h of exposure to...
