Description

technical field [0001] The invention belongs to the technical field of preparing semi-solid alloys, in particular to a wave-shaped inclined plate vibration device for preparing semi-solid alloys and a preparation method. Background technique [0002] Metal semi-solid forming technology was first proposed by Professor Flemings of the Massachusetts Institute of Technology in 1971. It is formed in the liquid-solid two-phase region of the alloy, which saves energy and materials, and has a short process. It has many advantages: small forming force, low energy consumption, and environmental protection; it is easy to produce complex parts near the net shape; the component segregation is less, and the life of the tool is obviously improved; it can produce particle and fiber composite materials. Known as the most promising green processing technology in the 21st century, it has attracted widespread attention. [0003] At present, the semi-solid forming technologies put into commerci...
