FeNiMnCu0.2Alx是一种具有简单的面心立方堆积结构的由多种合金熔融而构成的高熵合金。Al的添加量的不同会对其性能造成不同的影响,由于Al元素的含量会影响到FeNiMnCu0.2Alx的硬度值,因此可以通过控制Al元素含量这种办法来获得硬度合适的FeNiMnCu0.2Alx高熵合金。如果单纯控制Al含量还达不到高熵合金所需要的硬度,也可以尝试加入一些别的元素来进行调整和改变。主要利用的Materials Studio软件中的CASTEP的计算功能,对所构建的合金晶胞进行相形成能、态密度以及能带图的分析。找出其能量与原子分布的规律,为进一步研究提供理论依据。

FeNiMnCu0.2 Alx is a high-entropy alloy composed of a plurality of alloys and having a simple face-centered cubic stacking structure. The addition of Al will have different effects on its performance. The value of hardness FeNiMnCu0.2 Alx were affected by the content of Al element, and we can obtain the FeNiMnCu0.2 Alx high entropy alloy with the desired hardness by controlling the content of Al element. And if you can not find the hardness of your satisfaction in all sectors, you can also try to add some other elements to make adjustments and changes.This paper is focused on the calculation f...
