Abstract
In a grainboundaryengineered GBE microstructure Σ9 boundaries are the second most abundant boundary type This article presents data showing that in GBE copper most Σ9s were special Σ9 boundaries are also a geometrically necessary component of a GBE microstructure It is suggested that there are competing requirements for Σ9s during iterative GBE processing they are required to be mobile whereas afterward it is desirable that they are special boundaries
