Abstract

Two types of solid state reactions that occur during mechanical alloying of Mo/O —20 at. % Fe system with various oxygen concentrations were studied by Mössbauer spectroscopy and X‐ray diffraction. The first type of solid state reaction, Mo/O+Fe→bcc Mo(O)‐Fe, was observed for Mo samples with 8 at. % of oxygen. The second type of solid state reaction proceeds as Mo/O+Fe→bcc Mo(O)‐Fe+hcp Mo(O)‐Fe→bcc Mo(O)‐Fe+Am Mo(O)‐Fe for Mo samples with 14 at. % of oxygen and 1.6 at. % of MoO3 phase. The assumption about correlation between the second component dissolution rate and mixture components yield point ratio is confirmed.
