MANGANESE-LIKE METASTABLE PHASES IN THE Fe-Mo SYSTEM: EXPERIMENTAL STUDY AND THERMODYNAMIC MODELING. I. CRYSTALLINE STATE OF Fe-Mo MELT-SPINNING ALLOYS

摘要

The β-Mn structure (π-phase) is revealed on contact and free surfaces of Fe_(63)Mo_(37) melt-spinning ribbons. The full-profile analysis (Rietveld analysis) of diffraction patterns for a mixture of polycrystalline phases has identified, along with the metastable π phase, bcc solid solutions, μ and σ phases, and an intermediate bcc phase in the Fe-Mo phase diagram.
