Martensitic transformations and shape-memory materials

The authors review theoretical research on martensitic phase transformations in shape-memory materials, with emphasis on recently derived theory and predictions of interest for alloy development. Research on special lattice parameters corresponding to certain microstructures, complex crystal structures and 6M martensite, the relation of micro-scale to macro-scale deformations, ferromagnetic and ferroelectric martensites, and martensite at small scales is covered.
