Inorganic Materials Aims and scope

Abstract

Mixtures of the Mo5Si3 silicide with 1.1–2.4 wt % carbon were melted after reaction sintering and the formation of the Nowotny phase (Mo4.8Si3C0.6), and the effect of various heat treatments on the phase composition of the samples was studied. The crystallization of the melted samples leads to a reduction of the volume fraction of the Nowotny phase relative to that after reaction sintering, but subsequent annealing below the liquid phase formation temperature allows the volume fraction of Mo4.8Si3C0.6 to be again raised. We discuss possible causes of the observed phase transformations.
