摘要：

In situ transmission electron microscopy (TEM) experiments have been carried out on the Ti-6Al-4V alloy. This work focuses on the dislocation motion close to the alpha/beta interfaces. The interfaces influence the alloy strengthening by inhibiting the dislocation propagation but also by favouring the plastic deformation transmission. Results of deformation micromechanism dynamic are reported for the first time in this alloy at room temperature and compared to post-mortem TEM results. (c) 2007 Elsevier B.V. All rights reserved.
