The Role of the Boundary Plane in Grain Boundary Engineering

This paper reports new data on the distribution of grain boundary planes in commercially available GBE copper. The results show that nearly 60% of grain boundary length was Σ3, i.e. annealing twin related. There was a slightly enhanced proportion of {111} boundary planes, even after Σ3 boundary segments were excluded from the data set. There was a high proportion of boundary plane length on the...

Orientation Distribution of Σ3 Grain Boundary Planes in Ni Before and After Grain Boundary Engineering

The distribution of grain boundary plane orientations in polycrystalline Ni has been measured before and after grain boundary engineering. The grain boundary engineered microstructure has a relatively higher concentration of Σ3 grain boundaries and, when compared to the initial structure, more of these boundaries have orientations that are inclined by more than 10° from the (111) orientation of...

A new approach to grain boundary engineering for nanocrystalline materials

A new approach to grain boundary engineering (GBE) for high performance nanocrystalline materials, especially those produced by electrodeposition and sputtering, is discussed on the basis of some important findings from recently available results on GBE for nanocrystalline materials. In order to optimize their utility, the beneficial effects of grain boundary microstructures have been seriously...
