The difference in orientation noise between regions near low angle boundaries and grain interiors has been investigated. Orientation measurements were made on samples of high purity nickel (99.999%) cold-rolled to a reduction of 98% and then annealed at 800℃ to give a strong cube texture. A pattern quality type parameter shows lower pattern qualities from volumes near the low angle boundaries. However, despite these differences the orientation noise in near-boundary regions was not found to be significantly worse than that in grain interiors. A significant variation was observed in the orientation noise for grains of different orientation.
