Data: Effect of TCP phases on tensile properties of engineering alloys: Insights gained from a CrMnFeCoNi high-entropy alloy
Description
This data set contains the raw data of the article "Effect of TCP phases on tensile properties of engineering alloys: Insights gained from a CrMnFeCoNi high-entropy alloy" (https://doi.org/10.1016/j.actamat.2025.121530). The description and naming formats associated with each of the folders/files is provided alongside it. The general structure is as follows: (1) BSE images of the FCC+TCP-phase microstructure before deformation: This folder contains backscatter electron (BSE) micrographs, taken from the head of tensile specimens after tensile tests. This region represents an undeformed region, characteristic of the microstructure before testing. The micrographs were used to estimate the topologically close-packed (TCP) σ-phase area fraction from four representative micrographs. The listed states have been referenced in our Supplementary Table S1 (see, https://ars.els-cdn.com/content/image/1-s2.0-S135964542500816X-mmc1.docx) and some of the raw BSE micrographs were used to design Fig. 1 in the main article (https://doi.org/10.1016/j.actamat.2025.121530). (2) EBSD data of ruptured tensile specimens with a two-phase FCC + σ microstructure: This folder contains the raw (.ctf) files related to the electron backscatter diffraction (EBSD) scans presented in the research article (https://doi.org/10.1016/j.actamat.2025.121530). This includes EBSD raw data of tensile specimens deformed to rupture at room temperature (RT) and -196 °C with σ-phase area fractions of 0.27 and 0.20, respectively, both with an average grain size of ~50 µm. The images were recorded from the gauge of the tensile specimens far away from the region that experienced necking. These raw data were used to obtain Fig. 9 of the research paper as well as the Supplementary Figs. S16 and S17. Additionally, the folder contains the EBSD raw data related to a specimen with a finer grain size of ~2.5 µm and a σ-phase area percentage of ~6 % in the undeformed state, which was developed through subsolvus annealing (900 °C for 1h). These data were used to prepare the Supplementary Fig. S21. (3) Microstructural evolution during tensile testing obtained by in-situ BSE imaging: This folder contains BSE micrographs recorded during in-situ tensile tests from the gauge of the tensile specimen. The micrographs presented here were employed to design Figs. 8a, and S10-S15. (4) Tensile curves at RT and -196 °C of specimens with different σ-phase area fractions: This folder contains the raw and processed tensile data related to the tensile tests carried out and presented in the article. These data have been used to prepare Figs. 2, 7, 8a, 13, 14b, S1 - S4, S6-S15.
