Thermodynamic limits and kinetic probabilities during homogeneous nucleation in liquid Ag-Cu alloys

Novel kinetic phase diagrams for homogeneous nucleation during nun-equilibrium solidification of Ag-Cu alloys were evolved by stochastic modelling. The allowable undercoolings and the composition of the primary nucleating phase at any cooling rate and liquid composition could be read from these diagrams, The calculated values were found to lie within the thermodynamically permissible limits determined through construction of non-isothermal metastability held diagrams.
