The nucleation and growth behavior of γ and η precipitates in A286 alloy was investigated by micro-Vickers hardness test and transmission electron microscopy. The morphology and the crystallography of them were also discussed. The hardness of A286 aged at 893-1073 K for durations up to 720 ks was closely related to the mean size of γ precipitates. The growth kinetic of the γ precipitate in η-phase free region was explained by Lifshitz-Slyozov-Wagners theory for diffusion controlled growth at 993-1073 K. The activation energy for the growth of the γ precipitates was estimated to be 283 kJ/mol.
