Dynamic Propagation of Deformation Twins in Iron Single Crystals

- 論文の詳細を見る
A twin band was introduced on a definite position in an iron single crystal under an impact compression. The propagation velocity of the twin head was determined from the time interval of signals from two resistance strain gauges stuck on the trace of the twin band. The propagation velocity of the screw type twin head was found to be 2.5mm/μsec, which \vas substantially independent of temperature in the range -196°〜1+123℃. The signal from a strain gauge stuck in the neighbourhood of a twin trace showed that the stress around the head of a dynamically propagating twin was about one half of the applied stress. Such elastic disturbances around the twin head may determine the saturation thickness (〜2μ) of a dynamically propagating twin band.
