Abstract
5B70 aluminium alloy is strengthened by Sc and Zr. It has higher strength and plasticity than common aluminum alloy. Meanwhile, 5B70 aluminum alloy which is widely used as a structural material also presents some advantages, such as corrosion resistance, excellent formability, and weldability. In this study, the high-temperature deformation behavior of 5B70 aluminum alloy and the hot extrusion process of the complex end frame part were studied, and the deformation property of 5B70 aluminum alloy at elevated temperature was analyzed by the high-temperature compression test. The numerical simulation of hot extrusion of complex end frame part was carried out. Moreover, the optimal hot extrusion parameters of 5B70 aluminum alloy were obtained, and the hot extrusion property and microstructure evolution of 5B70 aluminum alloy were investigated.
