| Abstract Scope |
Recently, it has been more important to realize the higher combustion temperature of a gas turbine for air crafts. In order to attain that, it is necessary the material gets an excellent mechanical property like tensile strength. The grain size of the material has a large influence on the mechanical property. Therefore, it is imperative to predict recrystallization behavior under hot forging and heat treatment for controlling the grain size. In this study, we focused on Alloy 718 of a Ni-based superalloy and developed a prediction model for the fractions of dynamic recrystallization and the grain size under a large scale hot forging. The calculated results are good agreements with experimental results of the fractions of dynamic recrystallization and grain size. |
