Method for manufacturing solid-state composite additive for high-performance structural component

A solid composite additive manufacturing method for high-performance structural component, characterized in that the method comprises the following steps:

• the rod-shaped raw material of the solid composite additive is heated to a solid solution temperature, wherein the rod-shaped raw material is prepared by casting method;
• the rod-shaped raw material of the solid composite additive after solid solution is loaded into an extrusion die and extruding it into a set shape;
• the raw materials of the extruded solid composite additive is laid on a base plate layer by layer according to the track by rolling method to form a prefabricated billet of the solid composite additive;
• and
• the prefabricated billet is processed by numerical control to obtain metal part;
• the raw material of the extruded solid composite additive is laid on the base plate layer by layer according to the track by rolling method to form the prefabricated billet of the solid composite additive, specifically comprises the following steps:
• under conditions of set temperature and set deformation amount, the raw material of the extruded solid composite additive is pressed by roller or punch;
• after the raw materials of the extruded solid composite additive are connected with the base plate, the raw material of the extruded solid composite additive are stacked layer by layer according to the track to form the prefabricated billet of the solid composite additive.
