The quenching process of 7050 aluminum alloy aircraft forging has been simulated by FE soft ABAQUS. The cooling curves and distribution of quenching residual stress have investigated. The results show that both the rib and web parts have same distribution: compressive stress on the surface
tensile stress in the core of the T component. The distributions of both external and internal
