In this work, the interaction of the moving edge dislocation with obstacles in form of copper
atoms is studied using the molecular dynamics simulations. The samples are aluminum …

The effects of a vacancy on the chemical bonding strength of the (001) α-Al//(001) θ'interface
were systematically investigated by using the first-principles calculations. The migration …

In order to reduce the weight of car body, Al-Mg-Si-Cu alloys have been widely studied and
used to produce outer body panels of automobiles due to their favorable high-strength-to …

摘要利用DSC, TEM, 拉伸实验以及硬度测试等方法系统研究了时效路径对高Mg/Si 比Al-Mg-Si-
