Experimental data related to the publication: "Phase transformations in metastable β Zr15Nb alloy revealed by in-situ methods"

Data related to the research article "Phase transformations in metastable β Zr15Nb alloy revealed by in-situ methods" published in the Journal of Materials Science (Version of Record: https://doi.org/10.1007/s10853-025-11846-x). The article’s figures were produced solely from these datasets using the data processing methods described therein. The .tiff files of Debye-Scherrer rings (related to Fig. 2, 7 and 8) obtained as raw data from high-energy synchrotron X-ray diffraction are enclosed in the .zip file "HEXRD_rawdata_Zr15Nb.zip" including metadata files and the beamline log file "Zr15Nb_beamline_logfile.log". The .csv files contaning temperature evolution of the lattice parameters data ("Lattice_parameters.csv" - related to Fig. 3) and temperature evolution of molar volume data ("Molar_volume.csv" - related to Fig. 4) adhere to a similar structure. The first row specifies the phase, the second row shows physical quantities, and the third row contains units. The data themselves begin on the fourth row. The .csv file "DSC_ElResistance_ThExpansion.csv" contains temperature evolution data of differential scanning calorimetry, electrical resistance and thermal expansion (related to Fig. 4 and 5). The first row specifies the method, the second row shows physical quantities, and the third row contains units. The data themselves begin on the fourth row. High-resolution microscopic images (Fig. 6a-h) are available directly within the published article (both PDF and online versions). Experimental methods and conditions are described in detail within the article.
