The invention belongs to the technical field of friction stir
solid-phase deposition additive manufacturing, and particularly relates to a friction stir additive manufacturing device and method for a high-entropy
alloy particle reinforced aluminum matrix composite. Comprising an
extrusion deposition
system and a
continuous feeding system, and the
extrusion deposition
system comprises an
extrusion screw and a rotating shaft shoulder; the
continuous feeding system comprises a
raw material box, an
induction heater and a feeding roller; and a feeding
pipe of the
continuous feeding system is communicated with an extrusion screw rod of the extrusion deposition system. The device can achieve continuous feeding of raw materials with different particle sizes and efficient and rapid
solid-phase additive manufacturing, does not need a protective
atmosphere in the additive manufacturing process, can operate in the atmospheric environment, and has the advantages of being high in
raw material adaptability, high in additive
manufacturing efficiency, low in manufacturing and maintenance cost and the like. According to the method, through heating plasticization and continuous extrusion, a thermoplasticized mixed
raw material is deposited on the surface of a substrate to form a deposition layer, meanwhile, stirring friction is conducted on the deposition layer, and rapid preparation of the high-entropy
alloy particle reinforced aluminum-based
composite material additive body is achieved.
