Abstract

The results of X-ray structure analysis, electron diffraction, and resistivity measurement investigations of the plastic-deformation and thermomechanical-treatment effects on the B2 - R - B19'′phase transformations in the Ti50Ni47Fe3 alloy are presented. The correlation between the resistivity - temperature plots near the martensitic transformation, X-ray structure analysis data, and dislocation substructure evolution is detected. It is ascertained that martensitic transformation is depressed under large deformations. The plastic deformation drives the B2-phase crystal structure into the state that is more stable for transformation into a new crystallographic modification.
