Originální abstrakt

The response of three NiTi allotropes to compressive uniaxial loading was studied theoretically using density functional theory. In particular, structural transformations observed along the axial compression of the theoretically predicted ground-state (base-centered orthorhombic) structure, the orthorhombic transitive structure (prototype AuCd), and cubic austenite were thoroughly investigated. The results showed that the presence of relatively low compressive stresses made NiTi martensite energetically more favorable in monoclinic structures than in orthorhombic structures.
