摘要	The influence of aging treatment on microstructure and corrosion fatigue crack growth (CFCG) behavior of oil-grade nickel-base alloy 718 is investigated. The average grain size of alloy 718 increases after aging treatment. Isolated platelet delta phases are precipitated at some of the grain boundaries in aged specimens. The one-step aged specimen shows a uniform distribution of fine spherical gamma' and elongated gamma '' precipitates. However, the two-step aged sample shows much finer gamma '' precipitates. Aging treatment leads to lower CFCG rates of alloy 718. Nevertheless, no visible difference of CFCG rates is observed between one-step aged and two-step aged specimens. (C) 2015 Elsevier Ltd.
