Nanosized strain pockets are visualised and the displacements of the atom columns are quantified. A comparison is made with conventional high-resolution transmission electron microscopy images of point defect induced strains in Ni-Al alloys.[001] Cs-corrected HRTEM image of Ni 51.7 Ti 48.3 B2 austenite with highlighted nanosized strain pocket of a few nm in diameter.
