Abstract

In the present study, in situ phase transformation experiments have been carried out using neutron diffraction to monitor the texture evolution during the α→β→α phase transformation in Ti-6Al-4V with and without 0.4% yttrium additions. The aim of adding yttrium was to control β grain growth above the β transus by grain boundary pinning. In the present case, strengthening of the β texture, occurring during β grain coarsening resulted in strengthening of particular β texture components, which increases the likelihood of α texture modification by selective growth of α variants on the common (110) β grain boundaries into unoccupied large β grains.
