An alloy based on Ni3(Al, Cr), IC264, has been isothermally forged in the temperature range 950–1100°C and strain rate range 3×10-4 to 3.5×10-2 s-1. Stress–strain curves show flow softening for most forging conditions, suggesting dynamic recrystallisation, as does microstructural examination. Deformation modelling has been carried out using a simple constitutive relationship.
