Al-Mg-Si合金和Al-Mg-Si-0.6%Cu合金的内耗研究金曼1,杨丽丽1,夏朝峰1(1.上海市上海大学材料科学与工程学院)摘 要:采用低频力学谱仪对Al-Mg-Si合金和Al-Mg-Si-0.6%Cu合金的内耗进行了研究.结果表明:两种合金的内耗在加热过程先升高后降低.利用TEM对Al-Mg-Si合金和Al-Mg-Si-0.6%Cu合金的微观结构进行观察,显示合金内耗的变化是合金中的析出相和位错相互作用的结果.关键词:内耗； 透射电子显微镜； Al-Mg-Si合金； Al-Mg-Si-0.6%Cu合金......

Al-Mg-Si合金GP区的键络结构与界面能分析王庆松1,郑发农1,王兴林1,沈洋1,江安1(1.安徽省芜湖市安徽工程大学 数理学院)摘 要:运用固体与分子经验电子理论,计算Al-Mg-Si合金L10型GP区的价电子结构,运用硬球模型,对该体系的GP区(L10型)与基体之间的界面能进行预测.计算结果表明,GP区具有较强的共价键络,是该合金时效硬化的主要原因.GP区中Mg-Mg原子之间的结合倾向最大,是时效初期GP区形成片状的内在原因.GP区随时效温度升高而键强减弱,从而热稳定性降低.GP区与基体的共格界面能比基体晶粒间的界面能低,是GP区形成和生长的有利条件.关键词:金属材料； Al-Mg-Si合金； GP区； 价电子结构； 界面能......

of Al-Mg-Si alloy GAO Ying-jun, CHEN Hua-ning, WEI Na, WEN Chun-li, HUANG Chuang-gao (College of Physics Science and Engineering, Guangxi University, Nanning 530004, China) Abstract: Atomic bondings of U1 and U2 phases in Al-Mg-Si alloy during aging were calculated by using the EET theory and the improved TFD theory. The results show that the strongest bonding and the second strong bonding......
