The preparation of high performance aluminum alloy by semi-solid forming technology is one of the important research directions of aluminum alloy forming technology, and then the present status of aluminum alloy semi-solid forming technology is reviewed from aluminium alloy material using, semi-solid pulping process and application. then, research results: aluminum alloy obvious grain size, size is more uniform, the preparation of the fine equiaxial recrystallization organization of semi-solid slurry, obtain better mechanical properties. Finally, point out the problems in the current research, the future development direction of semi-solid forming of aluminum alloys is prospected.
