Plasticizing extrusion-forming preparation method for deformable beryllium aluminum alloy plate

The invention discloses a plasticizing extrusion-forming preparation method for a deformable beryllium aluminum alloy plate. The plasticizing extrusion-forming preparation method for the deformable beryllium aluminum alloy plate comprise the steps of material proportioning, mixing, extruding and blank discharging, degreasing and rolling. By adoption of the preparation method, the problems of specific gravity segregation, composition segregation and the like of the deformable beryllium aluminum alloy plate are solved, and the problem of non-uniformity of beryllium aluminum alloy on the microscale is also solved; and the beryllium aluminum alloy blank which is compact in structure and good in performance is obtained, and the subsequent plastic deformation capacity of the beryllium aluminum alloy blank can be improved easily.
