In situ TEM studies of the large plastic deformation of nanocrystalline gold nanowire
英文摘要
In this paper, the deformation behaviors of nanocrystalline gold nanowire were in-situ observed with homemade TEM double tilt tensile device. The nanocrystalline nanowires exhibit approximate 48% of homogeneous elongation ability. The in-situ TEM observation indicates that the ultra-large plastic deformation is realized through the coordination of grain boundary sliding and grain boundary migration. During the deformation process, the grain boundary sliding provides the large plastic deformation ability, which is at the mean time accommodates by the grain boundary migration.
