Notes:
The distribution of grain boundary plane orientations in polycrystalline Ni has beenmeasured before and after grain boundary engineering. The grain boundary engineeredmicrostructure has a relatively higher concentration of Σ3 grain boundaries and, when compared tothe initial structure, more of these boundaries have orientations that are inclined by more than 10°from the (111) orientation of the ideal coherent twin. Although the conventionally measured grainsize is not affected by the grain boundary engineering process, the average size of the regionscontaining only Σ3n grain boundaries increases by nearly a factor of two. The observations indicatethat the increase in the relative population of Σ3 grain boundaries results both from the preferentialelimination of random grain boundaries and the generation of new Σ3 grain boundaries which donot have (111) grain boundary plane orientations
