Abstrakt: In this study, the hot deformation behavior and deformation mechanism of Cu-18 wt.%Nb composite wire was studied based on the development of constitutive equations and hot processing maps. The constitutive equation of Cu-18 wt.%Nb composites was established based on the hyperbolic sinusoidal Arrhenius-type model, and the hot processing maps were developed using the principles of the dynamic materials model (DMM). In a view of microstructure refinement and work ability improvement, the optimum processing should be selected in the temperature range of 650–730 °C and the strain rate range of 0.001-0.1 s−1.
