چکیده انگلیسی
Commercially pure (CP) titanium samples were subjected to uniaxial compression of 3%, 10%, 20%, 30%, 40% and 50% reductions at room temperature (298â¯K), 673â¯K and 873â¯K respectively. {101¯2} type tensile twins were observed during the deformation at temperatures of 298â¯K and 673â¯K only. Volume fraction of these twins was increased up to 20% reduction beyond which it was decreased on further increasing the % reduction. The non-basal orientations had higher Taylor factor values and were prone to twinning. On the other hand near-basal orientations were observed to be the possible twinning products. It was further observed that the volume fraction of dynamically recrystallized grains was increased with increase in % reductions at high temperatures. The initial non-basal texture of the samples was found to be transformed to dominant basal texture after deformation irrespective of the temperature of deformation. An abrupt transition of texture from non-basal to basal at a true strain of 0.22 of the samples deformed at a temperature of 873â¯K was observed and this may be attributed to the nucleation and growth of tensile twinning.
