Sažetak

Strain energy as a part of the Gibbs free-energy change during the structural phase transition in small particles has been analysed. A special attention has been paid to the transitions that are characterized by small latent heats and large volume changes (large strains in the crystal lattice). Under the assumption that the dilatation of the nucleus of the phase just in formation causes plastic deformation of the particle, a new expression for the strain energy has been formulated. It shows that this energy may be greatly reduced if particles are sufficiently small.
