The development of future generations of Ni-base superalloys will depend on a systematic understanding of how each alloying element affects the fundamental properties of Ni-base superalloys, particularly with respect to their creep behavior. First, this article presents the temperature-dependent data of all factors entering into dilute impurity diffusion for 26 Ni-X alloy systems, including atomic jump frequencies, thermodynamic parameters, and diffusivity plots. Second, this article presents the data used to calculate the relative creep rate ratios showing the effect of each of the 26 alloying elements, X, on the dilute Ni-X alloy. The dataset refers to "A comprehensive first-principles study of solute elements in dilute Ni alloys: Diffusion coefficients and their implications to tailor creep rate" by Hargather et al. [1].
下一代镍基高温合金的发展将取决于对每种合金元素如何影响镍基高温合金基本性能的系统理解，特别是在其蠕变行为方面。首先，本文给出了26种Ni-X合金体系中所有参与稀杂质扩散的因素的温度相关数据，包括原子跳跃频率、热力学参数和扩散率图。其次，本文给出了用于计算相对蠕变速率比的数据，该数据显示了26种合金元素X中的每一种对稀Ni-X合金的影响。该数据集参考了Hargather等人[1]发表的《稀镍合金中溶质元素的综合第一性原理研究：扩散系数及其对调整蠕变速率的影响》。
