The kinetics of growth of the γ' precipitate in an lncoloy 907 alloy have been studied. The kinetics of particle growth obeyed the tirne law predicted by the Lifshitz-Wagner theory. The distribution of γ'particle sizes was found to be significantly broader than the theoretical distribution of LifshitZ-Wagner theory. It is suggested that this is due to the relatively large lattice parameter mismatch between γ' and the Fe-Ni-Co matrix
