| Abstract Scope |
Prior studies highlighted that interactions between slip bands and grain boundaries play a key role in the early damage stages in titanium alloys under a wide range of loading conditions including monotonic and cyclic tests. The understanding of such processes is thus a major concern for improving the microstructures and properties of these alloys. Slip activity in α grains of a deformed Ti-6Al-4V specimen with a bi-modal microstructure was analyzed. Operating slip systems were identified based on a slip traces analysis carried out using electron back-scattered diffraction and atomic force microscopy. In particular, the processes associated with interactions between slip bands and grain boundaries were investigated. The 3D geometry of the boundary, which was revealed using focused ion beam milling, was also considered. A quantitative analysis is presented based on slip step height measurement. |
