Microstructure and Properties of 7A99 Aluminum Alloy Forging after Two-step Aging Treatment

Effects of two-step aging treatment on the microstructure and mechanical properties of 7A99 forged aluminum alloy were studied using optical microscopy (OM), scanning electron microscopy (SEM), transmission electron microscopy (TEM), tensile test and fracture toughness test. The results show that af...
