【Abstract】 Aiming at the problems that aluminum matrix composite is difficult to deform plastically and there exists bad compatibility between reinforced phase and matrix metallic interface, the integrative technology of continuous solidification and forming for aluminum matrix composite was proposed to realize continuous near net shape forming of aluminum matrix composite’s pipe, wire and profile and to improve the compatibility and strengthening effect of particle phase and aluminum interface, reaching the goal of short stage and low energy consumption forming. Therefore, the microstructural evolution and product property of aluminum matrix composite during continuous solidification and forming were investigated, and solidification conditions were optimized.更多还原
