Mechanical Properties of Al-Cy-Mg alloys Micro-alloyed with Sn

摘要: The demand in aircraft and space industry for structural materials has resulted in a thrust in development of high strength and light weight alloys especially Al-Cu, Al-Mg-Si, and Al-Cu-Zn-Mg alloys [1]. The recent trend is to improve the mechanical properties of these alloys by microalloying with elements such as Sn, Cd, Ag, etc.[1-8]. In the present study, Al–Cu–Mg alloys microalloyed with Sn varying (Sn wt.% varying between 0 to 0.1) were processed by casting technique followed by rolling. The microstructure and mechanical properties of these alloys after heat treatment were investigated and reported.
