The Stability

Using linear perturbation methods, a precipitate–matrix interface stability criterion is obtained for dilute ternary systems. The calculation takes account of capillarity, transport in the precipitate, and ternary diffusional interaction. The general stability criterion contains a term reflecting the destabilizing influence of the solute gradients (i.e., the point effect of diffusion) and a term representing the stabilizing influence of capillarity. Two limiting cases are treated in detail—insignificant transport in the precipitate and negligible ternary diffusional interaction. It is demonstrated that in these two cases the two solutes behave in a cumulative fashion.

The sigmaNiMo( Al) phase was formed using Ni3Al/Mo diffusion couples at 1423, 1473 and 1523 K. The growth of formed phase and the concentration-distance profiles for each component in the diffusion couples were examined by electron probe microanalysis (EPMA). The activation energy for the parabolic growth of ? phase is found to be 525.3 kJ/mol. The concentration dependence and average ternary interdiffusion coefficients in single ?-NiMo(Al) phase were calculated, and the Arrhenius equations of the D for the ?-NiMo(Al) phase are calculated, the diffusional interaction between Ni, Mo and Al in ?-NiMo(Al) phase was studied by the crossinterdiffusion coefficients. Moreover, these results were utilized to explain the ? phase formation and growth in ?? phase.
