Abstract

Elastic properties of single crystals TiNi-TiFe stable to martensitic transformations (MT), undergo one B2-R and two B2-R-B19' MT are investigated by ultrasonic method. Different types of crystal lattice softening of alloys are established. Microdiffraction, X-rays and electron microscopic studies confirm that before MT crystal lattice becomes unstable to the displacements of the atoms on the static type of plane waves.
