Strength And Plasticity

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.

Thermal deformation process of H62 brass is studied, multi-scale simulations of macro-forming property and microstructure distribution are carried out for the hot-extrusion process of double cups part with flange utilizing numerical simulation technology, the process parameters are determined and the microstructure of extruded parts is predicted. The constitutive equation of H62 brass under high temperature deformation is established with isothermal compression test, and the results indicate that the flow stress accords to Arrhenius hyperbolic sine functions. The model of microstructure evolution during hot-deformation is founded and the influence of process parameters on microstructure is revealed. The microstructure prediction on extruded part shows that the simulated results agree well with the experimental results. The high-quality products are obtained using the optimal process parameters.
