“…Therefore, to minimize their effect on the results, only results for the middle of the angular segment are taken into consideration, as shown in Fig. 3 [6]. Rollers are assumed to be frictionless and do not rotate around their axes, the assumption being that the effect of friction can be neglected.…”

Abstract. In the aerospace industry, the turbine disk plays a crucial role. Controlling the average grain size during the hot forming of nickel-based superalloys such as Inconel 718 is critical for turbine disk production. Recrystallization is primarily responsible for evolution of microstructure during a hot forming process. In the current study, Finite Element Method (FEM) is employed to assess grain size evolution during an incremental disk rolling process. FEM simulations are used to obtain temperature, strain and strain rate distributions. Then, utilizing these deformation distributions, recrystallization and consequent average grain size distributions are calculated using Johnson-Mehl-Avrami-Kolmogorov (JMAK) equations. Simulations are conducted for different spindle rates of the workpiece. This process is sensitive to the temperature and meta-dynamic recrystallization. Results show that temperature increases with the spindle rate due to the inelastic heat generation. Also a higher grain size variation through thickness is obtained for the simulation with lower spindle rate since meta-dynamic recrystallization fraction is higher.
