Recent advances in the metallurgy and applications of superalloy 718 (S718) are examined in reviews and reports. Topics addressed include melting technology for S718, solidification control in VAR and ESR S718 ingots, application of a modified phase diagram to the production of cast S718 components, microstructural characterization of cast S718, the hot deformation behavior of as-cast S718 ingots, and the effects of starting condition on the aging response of as-forged S718. Consideration is given to the long-term stability of a wrought S718 disk, P/M S718 tubing produced by cold radial forging, laser cladding of Astroloy on S718, the mechanical properties and microstructure of fine-grain centrifugally cast S718, the phase stability and aging response of TiC-reinforced S718, and the analysis and elimination of time-dependent notch sensitivity in S718.
