Data for: New high-throughput approach to study interdiffusion in medium- and high-entropy alloys

In the present work, interdiffusion experiments were performed using quaternary medium-entropy alloys. Our alloys are labelled from A to D: A: Cr35Fe15Co15Ni35 (composition in at.%) B: Cr15Fe35Co35Ni15 C: Cr15Fe35Co15Ni35 D: Cr35Fe15Co35Ni15 The data are experimental EDX concentration profiles that developed during annealing for 100 h. Moreover, we also provide fits of these data that were obtained using a physically-based, phenomenological kinetic model (Please refer to https://doi.org/10.1016/j.intermet.2020.106789 for more details). The data are labelled as follows: For example in the Excel file entitled: AB, 1173K, exp the reader will find experimental EDX concentration profiles of Cr, Fe, Co, and Ni that resulted from diffusion annealing at 1173K for 100 h in the diffusion couple AB. As another example, the Excel file: CD, 1373K, fit refers to fitted concentration profiles after 100 h at 1373K for the diffusion couple CD

本研究中，我们采用四元中熵合金开展了互扩散实验。本研究所涉及的合金标记为A至D：
A: Cr35Fe15Co15Ni35（原子百分比，at.%）
B: Cr15Fe35Co35Ni15
C: Cr15Fe35Co15Ni35
D: Cr35Fe15Co35Ni15
本次公开的数据为经100小时退火后得到的实验性能量色散X射线能谱（Energy Dispersive X-ray Spectroscopy, EDX）浓度分布曲线。此外，我们还提供了基于物理的唯象动力学模型拟合得到的上述实验数据拟合结果（详细信息请参阅https://doi.org/10.1016/j.intermet.2020.106789）。
数据命名规则示例如下：例如名为「AB, 1173K, exp」的Excel文件中，包含了扩散偶AB在1173K下经100小时扩散退火后得到的Cr、Fe、Co、Ni元素的实验EDX浓度分布曲线。再如名为「CD, 1373K, fit」的Excel文件，则对应扩散偶CD在1373K下保温100小时后得到的拟合浓度分布曲线。
