Orientation relationship between $$alpha$$-phase and high-pressure $$omega$$-phase of pure group IV transition metals

Adachi, Nozomu*; Todaka, Yoshikazu*; Suzuki, Hiroshi; Umemoto, Minoru*

Scripta Materialia, 98, p.1 - 4, 2015/03

 Times Cited Count:17 Percentile:60.33(Nanoscience & Nanotechnology)

The deformation texture of the high-pressure $$omega$$-phase of pure group IV metals was investigated using neutron diffraction analysis. The $$<$$0001$$>$$$$omega$$ direction gradually aligned to the shear direction with an increase in the shear strain introduced by the high-pressure torsion process. The deformation texture suggested that the main slip system of the $$omega$$-phase was {11-20}$$<$$0001$$>$$$$omega$$. We experimentally observed the orientation relationships of the mechanically stabilized $$omega$$-phase with respect to the reverse-transformed $$alpha$$-phase, and determined that the relationship was similar to that proposed by Silcock and Rabinkin.
