KINETICS OF FIRST-ORDER PHASE-TRANSITIONS IN A SOLID-SOLUTION

A wide variety of characteristics during the stage of nucleation of a single atom phase in a solid solution is obtained under steady-state e xternal conditions for a broad range of sizes. These include, flux in the space of sizes, number of new phase particles and their distributi on function. A technique is put forward to account for the influence o f the elastic field, formed in the vicinity of the nucleated phase par ticles and interaction of the solute components in a solid solution on the kinetics of the phase transitions. The proposed theory is extende d to phase transitions when the nucleated new phase has the complex st oichiometric composition.
