Equal Channel Angular Deformation (ECAD) of As-Cast AM60 Magnesium Alloy
《Journal of Materials Science & Technology》2003年第6期513-515,共3页PengLUO XiaolinWU KenongXIA 
This work was supported,in part,by the China Scholarship Council under grant number 21852035;in part,was supported by the Australia Research Council.
As-cast AM60 magnesium alloy ingot with grains coarser than those of as-extruded AZ series is more liable to produce cracks under ECAD with severe shear strain. A feasible scheme of equal channel angular deformation (...
