This article presents the datasets gathered for the hot processing of three Ni-based superalloys intended for A-USC application, Haynes 214, Haynes 230 and Inconel 740H. Isothermal compression tests were conducted with a Gleeble 3500 at temperatures between 1000 °C and 1200 °C and strain rates between 0.01/s and 1/s to a full true strain of 0.7. The obtained true stress-true strain curves were used as basis for hot processing maps, linking temperature, stress and strain rate. Subsequently, all samples were sectioned through the geometric centre to provide microstructural information, captured using EBSD, as well as EDX for the evolution of secondary phases. Thermodynamic modelling was performed to validate compositions and mass fraction data from EDX measurements. These combined datasets help in understanding the deformation behaviour of a selected range of superalloys, under commercial processing conditions, aiding in process design optimizations and improvements. For complete interpretation of the data the reader should refer to the related publication "Comparative study of the hot processing behavior in advanced Ni-based superalloys for use in A-USC applications".
本文介绍了为用于超超临界（A-USC）应用的三种镍基高温合金Haynes 214、Haynes 230和Inconel 740H的热加工所收集的数据集。使用Gleeble 3500在1000℃至1200℃的温度和0.01/s至1/s的应变速率下进行等温压缩试验，直至达到0.7的全真实应变。所获得的真应力-真应变曲线被用作热加工图的基础，该图将温度、应力和应变速率联系起来。随后，所有样品均沿几何中心剖切，以提供使用电子背散射衍射（EBSD）捕获的微观结构信息，以及用于次生相演变的能谱仪（EDX）分析。进行了热力学建模，以验证能谱仪测量得到的成分和质量分数数据。这些综合数据集有助于了解选定范围内高温合金在商业加工条件下的变形行为，有助于工艺设计的优化和改进。欲完整解读这些数据，读者应参考相关出版物《用于超超临界应用的先进镍基高温合金热加工行为的比较研究》。
