摘　　要：高熵合金是一种新型结构合金,相比传统合金,它具有更优异的硬度、耐腐蚀性和抗拉强度等性能,具有很高的研究价值。通过大量的实验研究发现,高熵合金的制备方法多样,且不同的合金元素添加能够改变其整体的性能,如:Cr、Mo、Ti、B元素可以提高高熵合金的硬度,Mn元素则可提高电阻率,Al、Cr可以改变高熵合金的相结构,Zr元素可以增强高熵合金的晶格畸变等。本文综合现有的研究结果,总结了高熵合金的常用制备工艺以及各元素对于高熵合金的组织性能的影响。High-entropy alloys (HEAs) are a new type of structural alloy that exhibit superior properties such as hardness, corrosion resistance, and tensile strength compared to traditional alloys. Therefore, they have high research value. Through extensive experimental research, it has been found that HEAs can be prepared by various methods, and the addition of different alloying elements can change their overall properties. For example, Cr, Mo, Ti, and B elements can increase the hardness of HEAs, Mn element can increase their resistivity, Al and Cr elements can alter their phase structure, and Zr element can enhance their lattice distortion. This paper summarizes the common preparation processes of HEAs and the effects of different elements on their microstructure and properties based on existing research results.
