Description

Highlights: • Constitutive equation for interdependency of constitutive variables is formulated. • Apparent activation energy for hot deformation is close to activation energy of Ni. • The observations suggest diffusion of Ni as the rate controlling mechanism. • Significant grain refinement by dynamic recrystallization (DRX) is observed. • DRX along the initial grain boundaries showed no preferred orientation selection.
