Abstract:Here, we apply the electron backscatter diffraction (EBSD) technique to identify grain boundaries (GBs) in a metal sheet surface, and the metal sheet is subsequently deformed via contact with a hard nanomold. Quantified by the length of molded nanorods, combining with molecular dynamics (MD) simulations and transmission electron microscopy (TEM) characterization, the microstructure evolution and the important influence of individual GBs on plastic deformation during nanomolding of crystalline Ag at different temperatures and stresses are revealed. Diffusion-based mechanisms become dominant onc
