... there are three tetragonal variants of martensite for the cubic-to-tetragonal transformation ... the coexistence of several martensitic phases is at the basis of the intriguing shape-memory effect which occurs for example in nitinol: a deformation can be reversed upon heating. 5, record 1, English, - martensite

martensite: A metastable transitional structure formed by a shear process during a phase transformation, characterized by an acicular or needlelike pattern; in carbon steel it is a hard, supersaturated solid solution of carbon in a body-centered tetragonal lattice of iron. 2, record 2, English, - martensitic%20phase
