Abstract
The microstructure evolution of different stacking fault energy metal materials, copper, aluminum alloy and magnesium alloy during ECAP, were investigated based on the finite element simulation software DEFORM-3D. Analyzed the effect on the microstructure of deformation speed, extrusion passes and stacking fault energy. The results show that, the grain size is decreased with the pass number increasing, and deformation speed has no obvious effect on the microstructure. The high SFE metal, aluminum, shows a finer grains than the medium SFE metal, copper.
