X-ray diffraction and Mössbauer spectroscopy studies of a mechanosynthesized Fe75B25 alloy

“…Based on many works, it may be stated that the probability of formation of metastable phases during mechanical synthesis depends on the differences in atomic radii of constituents as well as electronegativity [1]. Recently, it was observed that for near-equiatomic composition of Fe-X p alloys (X p : Al, Si, Ge, and B) the formation of solid solutions, silicides, germanides and borides depends on the strength of covalent bonding of the p-element [2]. In the case of a metal-metal system with free electrons, that is, Fe-Al alloys, disordered solid solutions are mainly formed.…”

“…In the case of a metal-metal system with free electrons, that is, Fe-Al alloys, disordered solid solutions are mainly formed. Mechanical synthesis of Fe with semimetals (Si and Ge) with a high level of covalence leads to the formation of the ordered phases, that is, FeSi, FeGe 2 , -Fe 5 Ge 3 and FeGe [2].…”
