Abstract
Among the commercially available superalloys, 718 stands out as the most dominant alloy in production. Currently, 718 accounts for as much as 45 percent of wrought nickel-based alloy production and 25 percent of cast nickel-based products. As an introduction to the September International Symposium on Superalloys (the program precedes this article), the following focuses on 718’s status in four key areas: clean-melt practice, resistance to low-cycle fatigue, thermomechanical processing, and alloy optimization.
