| Semi-solid metal forming has a history of nearly 50 years and attracted much attention due to its processing advantages and market value. Many processing methods have been developed, among which the semi-solid rheological forming process has a good development prospect for its high efficiency and low cost. As the melting point of copper alloy is generally high, there are few researches on its semi-solid process. In this paper, the research progress of semi-solid rheological preparation technology for copper alloy was briefly reviewed, including the process of each new process, the selection of optimal process parameters and the mechanism of the process; and the existing problems of each process were analyzed. The new progress of the rheological preparation process model and its mechanism of semi-solid state were described, and the development trend was analyzed and prospected. It is considered that the future research direction of semi-solid rheological forming technology includes new preparation method of semi-solid slurry, new semi-solid alloy and semi-solid structure evolution mechanism as well as their control methods. |
