| 英文摘要 | The planar slip associated with the interaction between dislocations and a(2) precipitates in titanium alloys was investigated using atomistic simulation and transmission electron microscopy. The simulation reveals that dislocations experience different critical resolved shear stress (CRSS) during their passing through the a(2)-Ti3Al particle. The CRSS of the first pass increases linearly with the particle diameter both in the prismatic and basal planes, resulting in the formation of the anti-phase boundary within particle, which decreases the CRSS of the second pass. This triggers a slip planarity that ends up of dislocation pairs. The present results provide a deeper understanding on the plasticity and fatigue of titanium alloys containing a(2 )precipitates. |
