Abstract

The flow stress curves of Cu-1.0%Zr-0.15%Ce alloy during high temperature deformation were analyzed by using a Gleeble-1500D thermal simulation machine at the hot deformation temperature of 550 C, 650 C, 750 C, 850 C and 900 C, the strain rate of 0.001 s-1 0.01 s-1 0.1 s-1 1 s-1 10 s-1 , respectively. The results show that the hot deformation mechanism of the alloy is mainly based on the dynamic recovery under relative lower hot deformation temperature or higher strain rate. The thermal deformation mechanism of the Cu-1.0%Zr-0.15%Ce alloy is the dynamic recrystallization under relative higher hot deformation temperature or lower strain rate. The constitutive equation of the alloy was calculated and established respectively on the basis of the relationships among the flow stress, strain rates and deformation temperature. The thermal activation energy of the alloy is about 430.51 kJ/mol.
