论文摘要
引入了一种简单的拟合方法，用于建模第四纪和Quinary Face-Contim-Cent-Centim Cubic（FCC）实心溶液高熵合金（HEAS）在Co-Cr-Cr-Fe-Mn-Ni系统中。有人提出，固体溶液的强度可以通过多项式方程进行建模，其中使用实验数据来查找多项式的系数。据观察，所提出的多项式可以很好地模拟实体溶液的强度。组成元素对Quinary Co-Cr-Fe-Mn-Ni合金硬度的影响；结果表明，合金的强度随着FE含量的增加而降低。 FE的软化作用是通过考虑其对减少合金剪切模量的影响来解释的。此外，研究了混合和价电子浓度的参数焓对HEAS强度的影响。结果表明，混合的焓对Quinary Co-Cr-Fe-Mn-Ni合金的硬度具有明显的影响，并且随着混合焓的降低，强度会增加。此外，结果表明，随着参数价电子浓度的增加，Quinary Co-Cr-Fe-Mn-Ni合金的硬度增加。
A simple fitting approach is introduced for modeling the strength (hardness) of quaternary and quinary face-centered cubic (fcc) solid solution high entropy alloys (HEAs) in Co-Cr-Fe-Mn-Ni system. It is proposed that the strength of solid solution HEAs could be modeled by a polynomial equation where experimental data are used for finding the coefficients of polynomial. It is observed that the proposed polynomial could model the strength of solid solution HEAs very well. Effects of constituent elements on the hardness of quinary Co-Cr-Fe-Mn-Ni alloys are investigated; the results indicate that the strength of alloys decreases with increasing the Fe content. The softening effect of Fe is explained by considering its effect on decreasing the shear modulus of alloys. Furthermore, the effects of parameters enthalpy of mixing and valence electron concentration on the strength of HEAs are investigated. The results show that the enthalpy of mixing has a noticeable effect on the hardness of quinary Co-Cr-Fe-Mn-Ni alloys and the strength increases with decreasing the enthalpy of mixing. Furthermore, the results show that hardness of quinary Co-Cr-Fe-Mn-Ni alloys increases with increasing the parameter valence electron concentration.
