Title:
NI-CO-FE-B EUTECTIC HIGH-ENTROPY ALLOY, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/252541
Kind Code:
A1
Abstract:
Disclosed in the present invention are a Ni-Co-Fe-B eutectic high-entropy alloy, and a preparation method therefor. An alloy component of the eutectic high-entropy alloy is NiaCobFecBdMe, M being a microelement, wherein a, b, c, d, and e are respectively mole percent of corresponding elements, a > 15%, b > 15%, 5% ≤ c ≤ 10%, 10 ≤ d ≤ 25%, e ≥ 0%, and a + b + c + d + e = 100. The eutectic high-entropy alloy of the present invention is prepared by a suspension smelting method. The eutectic high-entropy alloy is a eutectic layer structure, and a non-metal main element plays an important role in a eutectic system. The interlamellar spacing is small, the strength and the plasticity are well matched, the mechanical property is excellent, the fluidity is strong, excellent casting performance is achieved, and the eutectic high-entropy alloy has broad application prospects in the fields of aerospace, mechanical industry and the like.
