论文摘要
高熵合金的屈服强度最近与测得的生平原子畸变相关。在这里,多组分合金中的均方根微阶段与进入溶质加强的预测模型的不合适 - 体积参数几乎成正比。分析两个模型三元合金家族,以面部为中心的立方CR-FE-NI和以身体为中心的Cutic NB-MO-V分析,证明了在广泛的组成空间上的相关性。因此,报道的屈服强度与微阶段的相关性是微脱位和不合适参数之间的相关性以及屈服强度对失差参数的衍生依赖性的结果。
The yield strengths of High Entropy Alloys have recently been correlated with measured picometer-scale atomic distortions. Here, the root mean square microdistortion in a multicomponent alloy is shown to be nearly proportional to the misfit-volume parameter that enters into a predictive model of solute strengthening. Analysis of two model ternary alloy families, face-centered cubic Cr-Fe-Ni and body-centered cubic Nb-Mo-V, demonstrates the correlation over a wide composition space. The reported correlation of yield strength with microdistortion is thus a consequence of the correlation between microdistortion and misfit parameter and the derived dependence of yield strength on the misfit parameter.
