Divided Flow Extrusion of AZ31 Magnesium Alloy with Cerium and Antimony Addition
Divided flow extrusion deformation behaviors and as-extruded tube properties of AZ31-Ce-Sb alloy were investigated. Addition of Sb and RE in AZ31 could accelerate the nucleation of dynamic recrystallization grains and refine tube microstructure. Compared to AZ31 Mg alloy, higher deformation temperature, extrusion speed and ration were allowed. AZ31-1%Ce-1%Sb alloy tubes had much better comprehensive performance.
