Flow Stress of Red Copper at Hot Deformation

This paper mainly studies the mathematical models for flow stress of red copper by doing experiment with a cam plastometer at a constant deforming rate. The paper provides many flow stress diagrams concerning red copper under different strain temperatures,different strain rates and different deformation degrees. At the same time, on the foundation of analyzing and comparing the regression results of nonlinear models, mathematical models of high accuracy for flow stress was put forward.
