HfZrTiTax high-entropy alloy, and preparation method and application thereof

The invention discloses a HfZrTiTax high-entropy alloy, and a preparation method and application thereof. The HfZrTiTax high-entropy alloy is mainly composed of Hf, Zr, Ti and Ta elements, wherein the mole ratio of Hf, Zr, Ti and Ta is 1:1:1:(0.16-1.29).The preparation method comprises the following steps: (1) weighing metallurgical raw materials; and (2) performing alloy melting on the metallurgical raw materials in an arc furnace under the conditions that the striking current is 250A and the melting current is 250-450A, stirring for 30-60 seconds after melting down for 5-6 minutes, overturning after the alloy is quickly cooled, and repeating such an alloy melting process for 5-6 times to obtain the HfZrTiTax high-entropy alloy. The HfZrTiTax high-entropy alloy disclosed by the invention has the advantages of excellent energy release characteristic, high strength, high density and high hardness, and can be used for an energetic structural material. 本发明公开了种HfZrTiTa高熵合金及其制备方法和应用。HfZrTiTa高熵合金主要由Hf、Zr、Ti和Ta元素组成，
