Effects of Ce on Extrusion Alloy Phase and Mechanical Properties of ZM21 Magnesium Alloy

In this paper, the effects of Ce addition on extrusion alloy phase and mechanical properties of extruded ZM21 magnesium alloy were investigated by the use of XRD, SEM and tensile test at room temperature et al. Analysis of the cerium magnesium alloy extrusion of ZM21 influence of alloy phase and mechanical properties and mechanism, The results show that of Ce can improves the mechanical properties such as ductility and strength, mainly due to deformation of the second phase in the alloy of Ce element formed by the fine grain structure and stability grain boundary sliding exert influence on the mechanical properties of the alloy when hinder plastic deformation.
