The characteristic of machined surface of high speed machining aluminum alloy 7050-T7451 is researched by micrographic experiments and analysis. The formation mechanics of machined metamorphism layer has been analyzed and studied. The dislocation-energy model in machined metamorphism layer was established and applied to explain the micrographic mechanics work-hardening using the thermo-mechanical coupling deformation theory and dislocation theory. The experimental results show that the interaction of high dislocation density effect on hardening is more remarkable than that of thermal stress in high speed machining.
