Hot Deformation Behavior of Superalloy 718

open access: yesSuperalloys 718, 625, 706 and Various Derivatives (1994), 1994
ABSTRACT The hot deformation behavior of Alloy 718 was characterized on the basis of the dynamic materials model and compression data in the temperature range of 900 to 1177°C and strain rate range of 0.005 to 5s’. The flow curves at all temperatures and strain rates showed little dependence on strains larger than 0.3.
