To achieve the numerical simulation of Cu-Be-Co alloy continuous extrusion and to develop a reasonable thermoforming parameters, the thermal deformation behaviors of Cu-Be-Co alloy were studied at deformation temperatures of 450 ℃~850 ℃ and strain rates of 0.1 s-1~10 s-1 by using Gleeble-1500D thermal simulation machine; The effects of hot compression on the microstructure were analyzed; The constitutive equation of Cu-Be-Co alloy hot deformation was established by using the Arrhenius equation; The results showed that the flow stress of Cu-Be-Co alloy is reduced with the reducing of the strain rate and the rising of the deformation temperature, and the dynamic recrystallization occurs for Cu-Be-Co alloy under high temperature conditions. ©, 2015, Beijing Res.
