Formation of stable and metastable phases under directional solidification conditions in materials showing peritectic phase equilibria is discussed. Based on interface response functions for single phase growth morphologies (dendrites and plane front) and on competitive growth arguments, a kinetic stabilization of metastable peritectic phases with respect to stable ones is predicted for various growth conditions. This method is applied to two industrially important classes of materials such as steels and Nd-Fe-B permanent magnets, the properties of which depend closely on the phases formed.
