The recently developed approach of combining automated crystal orientation mapping (ACOM) and in situ straining inside a transmission electron microscope was applied to study the deformation of nanocrystalline Pd x Au1- x thin films. This combination enables direct imaging of simultaneously occurring plastic deformation processes in one experiment, such as grain boundary motion, twin activity and grain rotation. Large-angle grain rotations with ≈39° and ≈60° occur and can be related to twin formation, twin migration and twin-twin interaction as a result of partial dislocation activity. Furthermore, plastic deformation in nanocrystalline thin films was found to be partialBeilstein journal of nanotechnology572-80https://www.ebi.ac.uk/biostudies/studies/S-EPMC4901548biostudies-literatureIn situ observation of deformation processes in nanocrystalline face-centered cubic metals.PMC4901548Hahn HKobler AKubel CBrandl CfalseIn situ observation of deformation processes in nanocrystalline face-centered cubic metals.The atomistic mechanisms active during plastic deformation of nanocrystalline metals are still a subject of controversy.
