temperature deformation[2, 4-5]. 7050 aluminum alloy, a typical Al-Zn-Mg-Cu series aluminum alloy, which belongs to precipitation- strengthened alloy, is widely used due to its high strength and low... belonging to low angle boundary can be observed clearly. Fig.2(c) shows the microstructure of 7050 alloy deformed to a strain of 0.3 at 350 ℃. Subgrain structure with clear boundaries can be found obviously......
