	The development of overgrown grains during sub-solvus annealing of a polycrystalline\&nbsp;\&gamma;\&minus;\&gamma;\&prime;\&nbsp;nickel-base alloy is investigated, with special emphasis on the primary\&nbsp;\&gamma;\&prime; precipitates. Quantitative analysis conducted on a large three-dimensional electron back-scattered diffraction dataset reveals a high fraction of\&nbsp;\&gamma;\&prime; precipitates on the annealing twin boundaries in the large grains. When observed in-situ in a scanning electron microscope, the formation of annealing twins is correlated to the crossing of\&nbsp;\&gamma;\&prime; precipitates by moving grain boundaries. The role of precipitates in the occurrence of growth accidents is discussed.
