An Investigation into the Kinetics of Formation of Inclusions during the Decomposition of Supersaturated Solid Solutions

The features of the formation of a system of microinclusions during the decomposition of supersaturated solid solutions are analytically described taking into account the size factor of interfacial surface energy. The suggested computation discloses the physical meaning of phenomena corresponding to phase transformation during the homogeneous and heterogeneous modes by which it proceeds. The supersaturation of the matrix phase is the determining characteristic of such a possibility at the stage of nanostructured nucleation. Unimodal and bimodal systems of microparticles can form at definite values of this quantity. Reliably established experimental facts confirm the conclusions of this theoretical analysis. The obtained solutions can be spread to the various bulk and surface systems of dispersed particles.
