- W2393716555 abstract "The hot deformation behavior of copper magnesium contact wire material CuMg0.3、 CuMg0.4 for high-speed railway was studied with electronic tensile strength tester Zwick /Roell Z100, at the temperature of 400 ～ 800 ℃ and strain rate of 0.01 ～ 0.2 /s.Results show that increasing temperature could improve the elongation and reduce the deformation resistance;Increasing strain rate could improve the elongation and the deformation resistance during hot deformation.Also the relationship between the stress with the deformed temperature and strain rate were calculated.Based on the Zener-Hollomon parameter,the steady flow stress model and hot deformation equation of copper magnesium material were proposed.According these,the simulation of continuous extrusion process for copper magnesium contact wire material has been done in the finite element software DEFORM-3D.Results of simulation are in good agreement with those of experiments.All these provide reference for the manufacturing process of hot forming." @default.
