Faceting–roughening transition of a Cu grain boundary under electron-beam irradiation at 300 keV

Abstract In this study, we examined the beam-irradiation effect on the structural evolution of the grain boundary (GB) in a Cu bicrystal at room temperature using a Cs-corrected, monochromated transmission electron microscope at an acceleration voltage of 300 keV. Faceting of the GB was observed at...
