A boundary between crystalline regions or phases. Its excess free energy depends on orientation, chemical bonding and lattice matching.
The excess free energy per interface area, specified for the phases, orientation, temperature and constraints.
An interface without extended one-to-one lattice registry; its local structure and energy differ from those of a coherent crystal interface.
An interface with largely matched regions separated by a network of misfit dislocations.
An interface whose lattice planes match continuously across the boundary. Elastic misfit strain can accumulate when the unstrained lattice parameters differ.
Elastic deformation required to match differing natural lattice spacings across a coherent crystal interface. Its energy can affect precipitate shape and loss of coherency.
