Abstract

The invention discloses a high-entropy alloy component and a manufacturing method thereof, and relates to the technical field of high-entropy alloys. The problem of composition segregation of the high-entropy alloys is avoided. The manufacturing method of the high-entropy alloy component comprises the steps that a substrate is provided; metal powder is laid on the substrate, wherein the metal powder comprises Al, Co, Cr, Fe and Ni with the atomic ratio being a: b: c: d: e, a is larger than 0 and smaller than or equal to 1.2, and each of b, c, d and e is equal to 1; and the metal powder is subjected to melting forming treatment through a selective laser melting process, and the high-entropy alloy component is obtained. The high-entropy alloy component and the manufacturing method thereof are used for manufacturing the high-entropy alloy component.

Description

technical field [0001] The invention relates to the technical field of high-entropy alloys, in particular to a high-entropy alloy component and a manufacturing method thereof. Background technique [0002] High-entropy alloys contain four or more components with close atomic ratios. From the perspective of thermodynamics, it has a high entropy value, resulting in a stable face-centered cubic (FCC) and body-centered cubic (BCC) alloy structure, which is unmatched by traditional multi-element alloys. It has a lattice distortion effect in structure and an atomic hysteresis diffusion effect in kinetics, so it is easy to obtain a simple solid solution with high thermal stability. Based on this, high-entropy alloys have generally high corrosion potential, corrosion resistance, high thermal stability, high temperature softening resistance, high temperature oxidation resistance, high strength and hardness, good wear resistance, high work hardening performance and high Excellent pr...
