  CrMnFeCoNi高熵合金中熵子系统的弹性模量和热膨胀系数

  摘要：

  摘要 作为 CrMnFeCoNi 高熵合金的中熵子系统的一组等原子合金（CrFeCoNi、CrCoNi、CrFeNi、FeCoNi、MnCoNi、MnFeNi 和 CoNi）的弹性模量被确定为 293 范围内温度的函数K–1000 K。在 100 K–673 K 的温度范围内确定了这些合金的热膨胀系数。所有合金都是单相的，具有面心立方 (FCC) 晶体结构，除了两相的 CrFeNi在 FCC 基体中含有少量体心立方 (BCC) 析出物的合金。此处获得的热膨胀系数和弹性模量的温度依赖性对于量化基本方面（如固溶强化）和结构分析/设计非常有用。使用上述结果，

  Chemical interaction and changes in local electronic structure of Cr, Fe, Co, Ni and Cu transition metals (TMs) upon formation of an $Al_8}Co_17}Cr_17}Cu_8}Fe_17}Ni_33}$ compositionally complex alloy (CCA) have been studied by X-ray absorption spectroscopy and X-ray photoelectron spectroscopy. It was found that upon CCA formation, occupancy of the Cr, Co and Ni 3d states changes and the maximum

  Cr x is found to increase linearly with increasing chromium concentration. Mossbauer spectra for Fe 0.75 Ni 0.25− x Cr x show that all the samples are magnetically ordered and some of them have a central paramagnetic line with a very low intensity (between 2 and 15%) for the samples with x =0, 0.05, and 0.10. However, Mossbauer spectra for Fe 0.65 Ni 0.35− x Cr x show that the sample with x =0 is magnetically

  摘要 Fe 0.75 Ni 0.25− x Cr x 的 X 射线衍射图表明，x =0 和 0.25 的样品形成晶格参数为 2.870 A 的单个 bcc 型相，而 x =0.05 和 0.10 的样品形成bcc 型相具有额外的 γ-fcc 相，作为具有 3.585 A 晶格参数的次要相。另一方面，所有 Fe 0.65 Ni 0.35- x Cr x 样品显示单个 γ-fcc 相。发现 Fe 0.65 Ni 0.35- x Cr x 的晶格参数随着铬浓度的增加而线性增加。Fe 0.75 Ni 0.25− x Cr x 的穆斯堡尔谱表明，所有样品都是磁性有序的，其中一些样品具有中心顺磁线，对于 x =0、0.05、0.05、和 0.10。然而，Fe 0.65 Ni 0 的穆斯堡尔谱。35− x Cr x 表明x = 0 的样品是磁性有序的，超精细场分裂在x = 0.05 开始坍塌，在x = 0

  A high-throughput technique can realize fast and efficient material screening, and greatly improve the discovery efficiency of advanced materials. In the present work, the gradient composition films of the W-Ta-CrFeNi high-entropy alloy were prepared by the three-target magnetron co-sputtering technique. The gradient alloy films exhibited a body-center-cubic (BCC) structure near the W or Ta element

  高通量技术可以实现快速高效的材料筛选，大大提高先进材料的发现效率。本工作采用三靶磁控共溅射技术制备了W-Ta-CrFeNi高熵合金的梯度成分薄膜。梯度合金薄膜在 W 或 Ta 元素靶材附近呈现体心立方 (BCC) 结构，在 CrFeNi 靶材区域附近呈现非晶结构。考虑过冷度的影响，非晶形成区（使用Ω ~ δ) 大于块状合金。这些合金薄膜表现出超高的纳米压痕硬度，最大硬度达到~20.6 GPa。高熵成分区的弹性模量低于低熵成分区。合金的纳米压痕硬度与混合熵之间存在非线性关系。该研究为高性能先进材料的开发提供了参考和替代材料库。

  Thermodynamic investigations on liquid ternary Fe-Ni-Cr alloys have been performed by means of the computer-aided Knudsen cell mass spectrometry. Ternary thermodynamically adapted power (TAP) series are used for the algebraic representation of the thermodynamic excess properties. At 1950 K, the molar excess Gibbs energy G(E) is negative in the predominant part of Gibbs triangle (minimum value: -2980 J/mol at x(Ni)=0.55, x(Cr)=0.45), and positive only near the liquid binary Cr-Fe alloys (maximum value: 940 J/mol at x(Cr)=0.375, x(Fe)=0.625). The molar heat of mixing H-E is exothermic for nearly all Fe-Ni-Cr melts (minimum value: -4770 J/mol at x(Fe)=0.38, x(Ni)=0.62). Only the Cr-richest ternary melts near the Ni-Cr binary alloys are slight endothermic (maximum value: 80 J/mol at x(Ni)=0.125, x(Cr)=0.87). The molar excess entropy S-E is slight negative for ternary Fe-Ni-Cr melts near the two binary boundary systems Fe-Ni and Cr-Fe with a minimum SE value of -1.27 J/mol K at x(Cr)=0.40 and x(Fe)=0.60, and slight positive at the side of binary Ni-Cr melts (maximum S-E value: 1.35 J/mol K at x(Ni)=0.50, x(Cr)=0.50).The Fe-activities of liquid ternary Fe-Ni-Cr alloys as determined, in this work, show slight negative deviations from the ideal behavior in the range of composition below the section of constant mole fraction x(Cr)/x(Ni)=1, and slight positive deviations from Raoult's law above this section line. The Ni-activities of all ternary Fe-Ni-Cr melts show negative deviation from the ideal behavior. The Cr-activities show slight positive deviations from Raoult's law in the range of composition on the left-hand side of the section of constant mole fraction x(Ni)/x(Fe)=1, and slight negative deviations from the ideal behavior on the right-hand side of this section line. The results of this work can be used successfully for phase-diagram calculations. (C) 1998 Elsevier Science B.V.
