In this work, the process of formation of metastable phases was investigated for the Fe75B25 composition. Mechanical synthesis was performed in a MAPF-2M high-energy planetary ball mill under an argon atmosphere. X-ray diffraction (XRD), differential scanning calorimetry (DSC), and Mössbauer spectroscopy (MS) were applied to recognize the phases. After 6 h of milling, the material consisted of two phases, that is, metastable tetragonal t-Fe2B and amorphous phases. During further thermal processing, the metastable phase was transformed into the stable Fe2B phase.

Solid state reaction and evolution of phase composition by milling of Fe50Ge50 powder mixture using two types of mills - Fritsch P-5 and figh energy MAPF have been studied. X-ray diffraction, Moessbauer spectroscopy and differential scanning methods were used for analysis of milling products. In different mills the chemical interaction between Fe and Ge occured in different ways. Final mechanically alloyed phase was nanocrystalline FeGe (B20) however the process of FeGe formation was completed after 100 h MA in Fritsch and after 2 h MA in MAPF.
