Raw data for: Magnetic response and hardness enhancement by spontaneous directional coarsening of Fe2AlB2 in quasicrystal-rich matrix

Preliminary part of the research was funded within the National Science Centre, Poland (NCN) research task No. 2018/02/X/ST5/02997 (Miniatura, based in Wroclaw University of Science and Technology, Poland - synthesis and thermal treatment, initial characterization).Most significant part of the data collected (magnetic, microstructural and atomic structure) was acquired within the National Science Centre, Poland (NCN) research grant No. 2020/36/C/ST5/00007 (Sonatina, based in the University of Wroclaw, Faculty of Chemistry, Poland). Hardness tests were performed from the PI's private funds. EBSD analyses were carried out at the Caltech GPS Division Analytical Facility, which is supported, in part, by NSF Grants EAR-0318518 and DMR-0080065.NV ODMR analyses were performed at the Department of Earth and Planetary Sciences, Harvard University, USA. The data contained within the dataset are only a part of data obtained within the mentioned projects that is associatd with one manuscript, that will be associated with the data after its publication.Miniatura project was aimed at determination, which alloy compositions can be doped with Si/B without causing the formation of other crystalline phases than the desired icosahedral phase and correlating this data with temperature stability, as well as determining changes in the quasi-lattice constant. This aimed to enable a more precise selection of alloy compositions in the subsequent Sonatina project. Sonatina project was aimed at development of the novel multi-phase aluminum-based alloy compositions that contain quasicrystalline phases and exhibit long-range magnetic order at near-room temperature. The task includes determination of structure, thermal stability and fundamental magnetic properties of the studied materials. Another aim was the unequivocal assignment of the investigated magnetic properties to the certain quasicrystalline microstructural phases of the chosen alloys.Person responsible for dataset preparation: Piotr Józef Bardziński ([e-mail], Department of Semiconductor Materials Engineering, WPPT, Wrocław University of Science and Technology, Wybrzeże Stanisława Wyspiańskiego 27, 50-370 Wrocław, Poland; former affiliation: Faculty of Chemistry, University of Wrocław, F.
