Abstract
It is well known that dislocations provide a very preferential nucleation points for thermoelastic martensitic transformation in shape memory alloys. Nevertheless, in ordered Cu-Al-Ni shape memory alloys, there is a coexistence of several kinds of dislocations, and their relative contribution during the martensitic transformation has not been clearly established. In this work we have studied by transmission electron microscopy the different dislocation families, in Cu-Al-Ni shape memory alloys, developed by deformation at several temperatures and after different thermomechanical treatments. The Low Angle Convergent Beam Electron Diffraction (LACBED) technique has been used because it becomes very convenient for highly anisotropic materials. We have also analysed the influence of such dislocation microstructures on the martensitic transformation.
