METHOD FOR MANUFACTURING SOLID-STATE COMPOSITE ADDITIVE FOR HIGH-PERFORMANCE STRUCTURAL COMPONENT

WIPO Patent Application WO/2022/089331

A1

A method for manufacturing a solid-state composite additive for a high-performance structural component. The method comprises: heating a rod-shaped raw material (2) of a solid-state composite additive to a solution temperature, wherein the rod-shaped raw material (2) is prepared using a casting method; loading the solution temperature rod-shaped raw material (2) of the solid-state composite additive into an extrusion die (3) and extruding the material into a set shape; laying the extruded raw material (4) of the solid-state composite additive, by using a pressure connecting method such as rolling, onto a substrate (7) layer by layer according to a trajectory to form a preform (6) of the solid-state composite additive; and numerically processing the preform (6) to obtain a metal component. The purpose of the solid-state composite additive manufacturing method for a high-performance structural component is to refine grains, break an oxide film, and solve the technical problem in solid-state additive manufacturing of high-density inclusions being easily introduced into the structural component, and therefore decreasing the mechanical properties of the structural component.
