  • 高熵合金(high-entropy alloys, HEAs)作为一种新型多主元合金, 原子排列有序、化学无序, 具有高熵、晶格畸变、缓慢扩散、“鸡尾酒”等四大效应, 表现出优异的组合性能, 有望作为新型高温结构材料、耐磨性材料、抗辐照材料应用于航空航天、矿山机械、核聚变反应堆等领域. 本文介绍了目前含钨HEAs的发展现状、常用的制备方法、微观结构和相组成. 针对HEAs优异的综合性能, 总结了目前含钨难熔HEAs的力学性能、抗摩擦磨损、抗辐照等性能, 对含钨难熔HEAs后续的研究方向进行了展望.

     

    As a new type of multi-principal component solid solution alloy, high-entropy alloy has the four major effects, i.e. high entropy, lattice distortion, slow diffusion, and “cocktail” in orderly arrangement of atoms and chemical disorder. It exhibits excellent comprehensive performances and is expected to be used as a new type of high-temperature structural material, wear-resistant material, and radiation-resistant material, which is used in the areas of aerospace, mining machinery, nuclear fusion reactors and others. In this paper, the present research status, conventional preparation methods, microstructures and phase compositions of tungsten high entropy alloys are mainly introduced. In view of the excellent comprehensive properties of high-entropy alloys, the mechanical properties, friction and wear resistance, and radiation resistance of tungsten high-entropy alloys are summarized, and the future research directions of tungsten high-entropy alloys are also prospected.
