Abstract

In situ straining in a transmission electron microscope was performed in order to investigate dislocation interactions with a prismatic loop, which as a mobile obstacle is expected to be displaced by the strain-field of dislocation prior to physical contact. It was found that when a gliding dislocation approached a critical distance, the prismatic loop was certainly attracted to the dislocation. The captured loop disrupted the dislocation motion and was not dragged along with the mobile dislocation. Instead, the dislocation bypassed the loop via cross-slip to another slip plane with a resolved shear stress estimated to be 40% lower than that of the original plane.
