Growth Kinetics of γ′ Particles in Incoloy 907

摘要

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
