▎ 摘　　要

NOVELTY - The method involves cooling the metal base melt to semi-solid to obtain a semi solid slurry, and mixing the semisolid slurry and the enhanced particle to obtain the semi solid slurry containing an enhanced phase. The semi solid slurry containing reinforced phase is cast and rolled by electromagnetic vibration to obtain metal-type composite plate. USE - Preparation method of metal-based composite plate e.g. metal or metal-base alloy. ADVANTAGE - The method improves the mechanical property of the metal-based composite plate, reduces the grain size of the composite plate and increases tensile strength and elongation at break. The method has simple structure and high efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a system device for preparing metal-based composite plate. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the system device for preparing the metal-based composite sheet material.
