Slip of c + a/2 Dislocations in Ti3Al Single Crystals Strained in Tension Along the C-Axis

  • Y. Minonishi (a1), M. Legros (a2) and D. Caillard (a2)

Abstract

In situ TEM straining experiments have been performed on a Ti3Al single crystal, along the c-axis, in order to study the slip of 2c+a dislocations in pyramidal planes. The results show that slip takes place in π1 planes, in contrast with what has been observed after compression tests (slip in π2 planes), and that rows of loops are nucleated in the slip plane. The mechanisms which may control slip in the π1 planes are briefly discussed.
