摘要: 高熵合金(High-entropy alloys,HEAs)是近年来新兴的一类先进金属材料,基于独特的多主元合金设计理念,有望突破传统单主元合金材料性能极限。其中,FeMnCoCrNi高熵合金是当前研究最为广泛的体系之一,具有优异的力学性能,应用前景广阔。本文首先介绍了高熵合金所具有的独特“四大核心效应”,包括高熵效应、晶格畸变效应、迟滞扩散效应、鸡尾酒效应;其次,重点综述了FeMnCoCrNi高熵合金在高温拉伸性能、高温蠕变性能及相应的变形机制方面的研究现状。

关键词: FeMnCoCrNi高熵合金, 高温拉伸性能, 蠕变性能, 变形机制

Abstract: As a class of emerging advanced metal materials in recent years and based on the unique multi-principal element alloy design concept, high-entropy alloys (HEAs) are expected to break through the performance limit of traditional single-principal element alloys. Among them, FeMnCoCrNi HEA is one of the most widely studied systems with excellent mechanical properties and broad application prospects. The unique “four core effects” of HEAs were firstly introduced, including high entropy effect, lattice distortion effect, hysteresis diffusion effect and cocktail effect. Secondly, the research status of FeMnCoCrNi high entropy alloy in high temperature tensile properties, high temperature creep properties and corresponding deformation mechanisms was reviewed.

Key words: FeMnCoCrNi high-entropy alloy, high temperature tensile property, creep property, deformation mechanism
