Solubility of substitutional impurities in decomposing alloys

摘要

Solubility of substitutional impurities in decomposing alloys with a cubic structure is calculated. The effect of elastic lattice vibrations on the decomposition and solubility is taken into account. It is shown that the temperature that corresponds to the peak in the decomposition curve is increased and the range of the biphase states is widened if the phonon effects are taken into consideration. The dependence of solubility on the decomposition parameter is determined; several particular cases of this dependence are analyzed. (C) 2004 MAIK "Nauka / Interperiodica".
