Thermodynamic functions that describe the processes both of consolidation of an assembly of dispersed particles and deconsolidation of a polycrystalline body are considered. Expressions have been derived for the shrinkage pressure, which arises from the consolidation of particles, and the migration pressure, which arises from deconsolidation of a polycrystalline body. The values of the shrinkage and migration pressures are described in terms of structure parameters of a composite body (particle size and shape, phase composition, values of surface tension at the solid-solid and solid-moving phase interfaces)
