The composition of a solid solution that is growing at conditions well away from equilibrium is not prescribed by equilibrium thermodynamics, but is determined kinetically. It depends both on the surface kinetics and on the transport of mass and heat to and away from the solidification front. In previous work, we have formulated a model for the kinetic or nonequilibrium segregation taking place at the solidification front enabling the construction of kinetic phase diagrams, which gives the growth composition of a solid solution as a function of the liquid composition and undercooling at the surface. In the present work, we extend this model to include both mass and heat transport, giving rise to effective kinetic phase diagrams. An overview of the tendencies in the calculated effective kinetic phase diagrams is given by scanning a large part of the parameter space, covering different types of materials, including metals, semiconductors, and molecular systems. We find striking and characteric differences in the relative contribution of the various processes to the effective segregation. For molecular mixtures, interfacial undercooling and heat transport limitation can be expected to be much more important than for metal and semiconductor mixtures where mass transport limitation is dominant.
