Abstract

The phase transformations of the alloy Ti-40 wt. % Nb after tempering and severe plastic deformation are studied. The phase transformations of the alloy according to the type and conditions of external influences were analyzed using methods of X-ray diffraction analysis, scanning electron microscopy and optical metallography. It has been determined that inverse phase transformation of the metastable α''-phase to equilibrium β-phase is carried out after severe plastic deformation. Complete phase transformation α'' → β is typical for the mode, which consists of three pressing operation with the change of the loading axis in cramped conditions, followed by a multipass rolling in grooved rolls.
