Refractory high-entropy alloy powder and preparation method thereof

The invention belongs to the technical field of metal materials, and particularly relates to refractory high-entropy alloy powder and a preparation method thereof.The refractory high-entropy alloy powder is composed of any two of Al, Cr and Nb, Ti, Zr and Mo, and the refractory high-entropy alloy powder is mainly of a body-centered cubic structure; the high-energy ball milling mode is adopted, alloying of high-melting-point metal at the low temperature is achieved through solid diffusion of all elements, melting of refractory metal materials is avoided, the impurity invasion rate is reduced, the preparation method has the beneficial effects that the steps are simple, components are easy to control, and the production efficiency is high, and the prepared refractory high-entropy alloy powder is nearly spherical and is suitable for large-scale production. The particle size of the powder is controllable (smaller than 10 microns), cost is low, and large-scale industrial application is facilitated. 本发明属于金属材料技术领域，具体
