Datasets on materials research of hard ferromagnet in TM-Fe-Si (TM = Ti, Zr, Hf, V, Nb, and Ta) ternary systems

The datasets presented in this article are related to mate-rials research on hard ferromagnet in TM-Fe-Si (TM = Ti, Zr, Hf, V, Nb, and Ta) ternary systems. The motivation for data collection is based on the research paper entitled "Novel hard magnetic phase with Zr11.5Fe53Si35.5 composition". The datasets are composed of scanning electron microscope im-ages, X-ray diffraction (XRD) patterns, and magnetization data for TM7Fe52Si41 annealed at 1050 degrees C. The chemical com-positions of constituent phases were determined by an en-ergy dispersive X-ray spectrometer (EDS). The phase analysis was performed using XRD and EDS results. The Curie temper-ature of each sample was obtained using magnetization data, and the coercive field was determined for hard ferromagnet samples Zr7Fe52Si41 and Hf7Fe52Si41. The datasets would be useful for developing an Fe-based rare-earth-free permanent magnet, which is one of the central issues of materials sci-ence. (c) 2022 The Author(s). Published by Elsevier Inc.
