论文摘要
我们报告了磁性特性，电阻率和Vickers的微度和退火的高渗透合金（HEAS）Feconipd和Feconipt的微度，并以面部为中心的立方结构。 800 $^{\ circ} $ c的热处理不会在很大程度上影响每个HEA的物理特性。库里温度和50 K时饱和矩的值为955 K，1.458 $μ__\ MATHRM {B} $/F.U。对于退火的Feconipd，以及851 K和1.456 $μ__\ MATHRM {B} $/F.U。分别为退火的粪便。每个HEA都是软铁磁铁，显示金属电阻率。两种HEAS的电子结构计算都支持铁磁接地状态。实验值和理论值之间的比较是在居里温度，饱和力矩和残余电阻率的情况下进行的。退火的Vickers微硬度和粪便均为188 HV。这些HEAS的每个原子图的硬度与价电子计数（VEC）在很大程度上不会偏离预期的通用关系，该关系形成了VEC $ \ sim $ 6.8的宽峰。这项研究将为设计具有高硬度的柔软的铁磁HEA提供一些暗示。
We report the magnetic properties, electrical resistivity, and Vickers microhardness of as-cast and annealed high-entropy alloys (HEAs) FeCoNiPd and FeCoNiPt with the face-centered cubic structure. The heat treatment at 800 $^{\circ}$C does not largely affect the physical properties in each HEA. The values of the Curie temperature and the saturation moment at 50 K are 955 K and 1.458 $μ_\mathrm{B}$/f.u. for the annealed FeCoNiPd, and 851 K and 1.456 $μ_\mathrm{B}$/f.u. for the annealed FeCoNiPt, respectively. Each HEA is a soft ferromagnet and shows metallic resistivity. The electronic structure calculations of both HEAs support the ferromagnetic ground states. The comparisons between experimental and theoretical values are made for the Curie temperature, the saturation moment, and the residual resistivity. The Vickers microhardness of annealed FeCoNiPd and FeCoNiPt are both 188 HV. The hardness vs. valence electron count (VEC) per atom plot of these HEAs does not largely deviate from an expected universal relation forming a broad peak at VEC$\sim$6.8. This study would give some hints on designing a soft ferromagnetic HEA with high hardness.
