Description

technical field [0001] The invention relates to the technical field of high-entropy alloy additives, in particular to a high-entropy alloy additive manufacturing device and an additive manufacturing method. Background technique [0002] High-entropy alloy is a high-entropy single-phase solid solution alloy, an alloy formed by five or more equal or approximately equal amounts of metals, the fracture resistance, tensile strength, corrosion resistance and oxidation resistance of high-entropy alloys Both are better than traditional alloys. Because high-entropy alloys have many desirable properties, they have received considerable attention in materials science and engineering. The traditional manufacturing methods of high-entropy alloys are mostly made by vacuum casting or metallurgical sintering, but these methods are complex and require several process steps, and due to the limitations of traditional manufacturing processes, the geometry of the samples that can be prepared is ...
