STEM Optical Sectioning for Imaging Screw Dislocations Core Structuresnin BCC Metals
Original language description
It is well known that the low-temperature plastic deformation of Body-Centred Cubic (BCC)nmetals is controlled by the glide of 1/2[111] screw dislocations. Their low mobility is causednby the delocalized nature of their cores which are extended into several planes in the zonenof the Burgers vector. This non-planar core spreading has been demonstrated by a number ofnatomistic studies made in the last 46 years. However, attempts at experimentalnobservation have been hindered by the Eshelby twist effect. The aim of this work is toninvestigate whether the edge and screw displacements associated with 1/2[111] screwndislocations in BCC metals can be detected by optical sectioning in high-angle annular dark fieldn(HAADF) Scanning Transmission Electron Microscope (STEM) imaging conditions.
