• Different ∑3n generation mechanisms for two post-deformation recrystallizations.
• New twinning mechanism is active for metadynamic and static recrystallization.
• ∑3 regeneration mechanism is predominant for static recrystallization.
The present research studied the grain boundary character distribution in Incoloy 800 H corresponding to two different post-deformation recrystallization mechanisms through uniaxial hot compression test and electron backscattering diffraction analysis. The results showed that the recrystallized grain size following metadynamic and static recrystallization was modestly larger than that from static recrystallization. Besides, two different mechanisms were responsible for the generation of Σ3n boundaries. In the static recrystallization samples, ∑3 regeneration was more active than new twinning formation. However, the new twinning would become predominant when metadynamic and static recrystallization took effect simultaneously.
