Abstract Scope Metastable states can be accessed experimentally due to limitations on the nucleation and growth kinetics of stable phases. The kinetic limitations are enabled by large undercooling, high supersaturation, rapid transformation and during the initial stage of interface reactions. At the same time the application of metastable phase equilibrium data can serve as valuable input in the evaluation of stable phase equilibria and in the analysis of microstructure development. For example, during solidification of undercooled liquids metastable phase equilibrium data has allowed for the formulation of more accurate Gibbs energy functions for the stable equilibria and has uncovered previously missed stable equilibria. During rapid transformation, thermodynamics sets the limit on the supersaturation in the product phase in terms of the T0 curves. Similarly, during the initial stage of interface reaction the phase selection including amorphous phase formation can be effectively analyzed by the relevant metastable phase equilibria.
