Abstract

A model of the bcc → hcp phase transition has been built, in which the {112} crystallographic planes shift in the 〈111〉 and 〈112〉 directions. The shift in the 〈112〉 direction leads to contraction, while the shift in the 〈111〉 direction causes pure shear. Numerical values of the deformation anisotropy during the phase transformation have been obtained. High-temperature X-ray diffraction and dilatometry data have been obtained to estimate the strain during the bcc → hcp phase transition in VT1-0, VT6, and VT41 titanium alloy samples.
