Abstract

The incidence of perfect glide dislocations, moving on parallel pyramidal slip bands on a particular grain boundary of deformed Titanium is studied by means of Transmission Electron Microscopy. Static experiments, performed by using the electron beam as a heating source, proved that slip propagation across the interface is possible when the angle of intersections between the activated slip planes of the incoming and the outgoing dislocations with the boundary plane is minimised. Additionally, the Burgers vector of the residual dislocations left in the boundary after slip transmission occurred should also be minimised. Due to their very small Burgers vector, residual dislocations are visualised with satisfactory results by an image simulation method.
