A nickel base superalloy which is widely used in power generation applications, Alloy 718, has been studied by analytical electron microscopy in order to elucidate the development of the complex microstructure which is produced during a typical multistage thermal treatment. The distribution of {delta}, {gamma}{double prime}, {gamma}{prime} and Laves phases was found to be strongly dependent on aging treatment. 7 refs., 5 figs.
