Study on Hot Deformation Behavior and Bending Forging Process of 7075 Aluminum Alloy

7075 aluminum alloy forged elbow has a wide range of application, but its deformation law is very complex. Its forging process parameters are difficult to control, so it is becoming a difficulty in practical production. In this paper, aiming at the forging parameters of 7075 aluminum alloy, the thermal simulation compression tests with different deformation parameters were cleverly designed, and the optimal forming range of 7075 aluminum alloy was obtained by combining theoretical calcu-lation, microstructure and simulation. The results showed that: 7075 aluminum alloy forming process parameters range was 350 degrees C <= T <= 450 degrees C + 0.01/s <=? <= 0.78/s, T = 400 degrees C + 0.78/s <= ? <= 1.0/s(except 400 degrees C + 0.1/s). The optimum forging parameters were: forging temperature 420 degrees C, forging speed 10 mm/s.
