Grain boundary engineering is known to increase both the fraction and connectivity of special Σ3n type boundaries. One of the newer metrics for connectivity is the idea of twin-related domains, which are essentially clusters of grains continuously connected by Σ3n type boundaries. Grain boundary engineered materials have previously been shown to possess very large twin-related domains, and their length scale has been tied to improved properties like fracture and corrosion resistance. We have tracked the development of large twin related domains through an iterative grain boundary engineering technique. Their relative size at each stage of processing is linked to the increasing Σ3n fraction and also the evolving network topology. These results will be compared to conventionally processed materials and the effects on mechanical properties will also be discussed.
