AbstractNot too long ago, the authors found that twinning can be a very slow process (i.e. many orders of magnitude lower than the speed of sound) and contribute to low-temperature (<0.25Tm) creep deformation behavior in single-phase HCP titanium alloys. Since then, it has been shown that this time-dependent twinning behavior can also be found in BCC titanium alloys. Furthermore, the time-dependent twinning was also found to play a significant role in the two-phase α + β titanium alloys. The extent of twinning and its contribution to creep behavior was found to depend on the grain size in the single-phase titanium alloys. In regard to single-phase beta alloys, the stability of the beta-phase was also found to play a significant role in twin...
