Effects of progressive solution treatment on microstructure and mechanical properties of 7055 alu-minum alloys were investigated. The results reveal that the tensile strength and yield strength of the 7055 aluminum alloy are improved with the slight decrease of elongation after progressive solution treatment. Meanwhile, microstructure of the treated alloy with u-niform and fine grain can be observed by OM (optical microscope) and SEM (scanning electron micro-scope).
