Abstract
Equations suitable for computing specific interfacial energies of precipitates dissolving by a first order transformation were developed on the basis of the singularities taking place at the critical temperature,T c, under equilibrium conditions. These equations employ data which can be determined by differential scanning calorimetry. Also the conditions for reaching dynamic equilibrium of particle volume fraction belowT c are analysed in terms of a maximum permissible experimental heating rate. The results obtained for disperse order inαCu-Al alloys are in good agreement with those expected from the observed particle features.
