Study of energy versus misorientation for grain boundaries in gold by crystallite rotation method. I. (001) twist boundaries
Small gold crystallites (approx. 50 to 80 nm dia) were welded to thin film (001) single crystal gold substrates at a series of predetermined (001) twist angles in the range 0 to 45/sup 0/. A pure (001) twist boundary therefore existed in each welded neck region which could be observed directly by transmission electron microscopy at normal incidence. Upon annealing, the crystallites rotated around (001) when the boundary energy varied with theta. The crystallites rotated into three misorientations corresponding to the special ..sigma..1 and ..sigma..5 misorientations and a symmetry related misorientation at theta=45/sup 0/. These results indicate the existence of grain boundary dislocation (GBD) related cusps on the boundary energy versus theta curve at ..sigma..1 and ..sigma..
