Mechanical behaviour of 7A04 aluminum alloy under different heat treatment process

摘要

High strength aluminum alloy of 7A04 is an important structural material,which is widely applied in aviation and spaceflight structures.Since its mechanical properties are strongly affected by the corresponding heat treatment process,many efforts are placed on trying to clarify their relationships between the heat treatment process and the consequence mechanical performance in the current study,where three heat treatment processes are mainly discussed.
