dc.description.abstract | Experiments were conducted on Ti-based alloys including a commercially pure titanium (& alpha; phase), Ti-6Al-4 V (& alpha; + & beta; phase) and TiNi (B19'-martensitic phase) alloys in order to investigate the phase transformation during highpressure torsion (HPT) at room temperature. An allotropic & alpha; to & omega; phase transformation in the commercially pure titanium occurred during HPT processing but increasing the rotation speed led to a decrease in the volume fraction of the & omega;-phase. This procedure facilitates the loss of the & beta; phase in the Ti-6Al-4 V alloy and promotes a B19' to B2 (austenite) phase transformation in the TiNi alloy. The results show that the bulk temperature increment in the processed specimens was not sufficiently high to affect phase transformations. However, the calculations by assuming adiabatic conditions revealed that the local temperature increment is responsible to encourage or suppress the phase transformation in the Ti-based alloys. This fundamental understanding of phase transformations during severe plastic deformation is useful for conducting microstructure engineering of Tibased alloys by tailoring the microstructures containing different phases and thereby producing different mechanical and functional behaviors. | - |
