Method for additive manufacturing of high-entropy alloy part through metal wires

Abstract

The invention discloses a method for additive manufacturing of a high-entropy alloy part through metal wires. The method comprises the specific steps that (1) a three-dimensional module of the to-be-manufactured high-entropy alloy part is established on a computer, and a processing route program is established according to the three-dimensional module; (2) the metal wires of different types required by the to-be-manufactured high-entropy alloy part are combined into a wire rope which is fed into a wire feeding device or a multiple-channel wire feeding device, the wire feeding speed, heat source energy, the scanning speed and protection gas flow are set, and additive manufacturing is conducted through special additive manufacturing equipment or a robot or a numerical control machine tool ormanual work at protective atmosphere or under protection of submerged-arc welding flux; and (3) the high-entropy alloy part is obtained through subsequent treatment of machining, heat treatment, surface treatment and the like on a part blank obtained through additive manufacturing. The method disclosed by the invention is simple and easy to conduct, low in cost and suitable for industrial production of the high-entropy alloy part.

Description

technical field [0001] The invention relates to a method for preparing high-entropy alloy parts through additive manufacturing technology using pure metal or intermediate alloy wire, which belongs to the field of preparation and processing of high-entropy alloys or multi-principal alloys, and also belongs to the additive manufacturing of metal materials technical field. Background technique [0002] High-entropy alloys are a new type of alloy system, also known as multi-principal alloys or multi-element alloys, generally composed of a variety of metal (non-metallic) elements in equimolar ratio or near equimolar ratio. Due to the high entropy effect of mixing multiple elements, the formation of intermetallic compounds is inhibited. High entropy alloys generally consist of simple face-centered cubic solid solution (FCC), body-centered cubic solid solution (BCC) or hexagonal close-packed solid solution (HCP) phase. composition. Compared with traditional alloy systems based on...
