Notes:
Normally, deformation twinning is a process that occurs at rates approaching the speed ofsound in bulk metals once a critical stress has been reached. However, recently it has been shownthat twins grow at speeds many orders of magnitude lower than the speed of sound during roomtemperature creep of titanium alloys. The net result is that this twinning process can contribute tothe low-temperature (less than 0.25*Tm) creep behavior of α, α−β, and β−titanium alloys. Forexample, α-Ti alloys with small grain size do not extensively deform by twinning and hence showlittle overall creep strain. These recent developments are reviewed in this paper.
