| Abstract Scope |
The focus of this study is on the microstructural evolution of the γ-γ' nickel-based superalloy René 65 under monotonic and incremental deformation paths. Here, incremental deformation is defined as the alternation of small deformations and short dwell times, representing the deformation path processed during a ring rolling. Incremental and monotonic deformation paths are performed using hot torsion and hot compression experiments and their resulting microstructures are compared. For a given final strain, strain rate and temperature, a monotonic deformation generates a higher fraction of recrystallization than an incremental deformation path does, for both torsion and compression experiments. Further experiments on interrupted incremental and monotonic compression deformation conditions are conducted to better understand the impact of dwell time on recrystallization. Static recovery and γ' precipitation evolution are two potential microstructural mechanisms discussed in this paper that could occur during dwell time and slow down the recrystallization evolution for incremental deformation conditions. |
