Conventional uniaxial compression test, designed to yield an effective strain of similar to 1, was carried out to understand the deformation mechanism of severely deformed commercial pure titanium at various temperatures. TEM analysis showed that only [10 (1) over bar1] twins accompanied with (a) slip dislocations were activated on non-basal planes in samples compressed at 573 and 623 K. In particular, the whole area of the sample compressed at 623 K were covered with [10 (1) over bar1] twin bands with a width of 200 nm. However, (a + c) slip instead of [10 (1) over bar1] twinning were found in samples compressed at 673 and 823 K. This indicates that [10 (1) over bar1] twinning plays an important role in accommodating severe plastic strain before the activation temperature of (a + c) slip.
