The semi-solid forming process is an important method for the production of high-performance aluminum alloy components. The semi-solid aluminum alloy has excellent fluidity and moldability, and can obtain complex parts with high precision and excellent mechanical properties. However, the formation of the semi-solid microstructure of aluminum alloy needs to be controlled within anarrow temperature range, and needs to be maintained for acertain period of time, which requires ahigh level of equipment and process control. In order to improve the efficiency of the semi-solid forming process and improve the performance of aluminum alloy components, it is necessary to explore new technologies that can accelerate the formation of semi-solid microstructures. In recent years, the application of pulsed magnetic fields and tilted tubes in aluminum alloy semi-solid forming has attracted more and more attention. The pulsed magnetic field has the advantages of fast heating rate, uniform heating, and short processing time. The tilted tube plays arole in controlling the microstructure of the semi-solid aluminum alloy by providing agradient of shear force during
