The effect of deformation temperature on the microstructure evolution of Inconel 625 superalloy

► The relationship between the stable DRX grain size and peak stress can be expressed by a power law function. ► Deformation temperature has a significant influence on the nucleation mechanisms of DRX at different deformation stages. ► With increasing the deformation temperature, the effect of DDRX accompanied with twinning formation grows stronger, while the effect of CDRX grows weaker.
