Research Progress of Al Alloy Semisolid Forming Technology

With the rapid development of science and technology and the economy, the demand for high-quality aluminum alloy casting is urgent in the fields of aviation, aerospace, military, and electronics industry technology. Preparation of high-quality aluminum alloy by semi-solid forming technology is one of the important research directions of aluminum alloy forming technology. The present status of aluminum alloy semi-solid forming technology from three fields, including aluminum alloy material used, a semi-solid pulping process, and application was introduced. The problems existing in the current research were pointed out, and the future development direction of the semi-solid forming of aluminum alloys was prospected.
