Kinetics of Reaction Interaction Between Molybdenum and Iron–Tin and Iron–Copper Melts

  • Published:
Powder Metallurgy and Metal Ceramics Aims and scope

The solubility of molybdenum in Fe–Cu and Fe–Sn melts and the growth kinetics of Mo6Fe7 layer at the molybdenum–melt interface at 1200°C are examined. The solubility of molybdenum in these melts is well described by the following equations: lgCMo = (–3.957 ± 0.176) + (25.77 ± 7.94) XFe –– (143.02 ± 77.92) XFe 2 (Fe–Cu melt) and lgCMo = (–2.783 ± 0.011) + (7.563 ± 0.111) XFe –– (10.844 ± 0.245) XFe 2 (Fe–Sn melt). The melt composition (atomic fractions) in the three-phase Mo–Mo6Fe7–melt equilibrium is established: 6.4 · 10–3 Fe, 1.64 · 10–4 Mo, and Cu being the rest (Fe–Cu melt); 0.046 Fe, 3.48 · 10–3 Mo, and Sn being the rest (Fe–Sn melt). The substantial difference between the growth rate constants in the melts, kFe–Sn >> kFe–Cu, at the same iron activity a Fe is attributed to the effect of admixtures (Cu and Sn) on the growth of the Mo6Fe7 layer. Data on the solubility of molybdenum in Fe–Cu and Fe–Sn melts and the growth kinetics of Mo6Fe7 in these melts are obtained for the first time.
