Abstract
The premartensitic structural evolution in and the mechanical properties of alloys based on titanium nickelide and other titanium-based intermetallics with a B2-type lattice are studied. The unique mechanical properties of titanium nickelide (anomalously high plasticity, superelasticity) are found to be caused by the realization of specific structural states (SRDO, IDS, R phase) and the formation of a domain nanostructure in the premartensitic state. The dynamics and crystallographic geometry of premartensitic phenomena determine the fine structure of the B2 phase and, quite often, the radical differences in the properties of intermetallic-based alloys with different degrees and systems of alloying.
