Effect of V on the microstructure and mechanical properties of Mg-10Er-2Cu alloy with a long period stacking ordered structure

Abstract : In this study, the effects of a trace amount of vanadium (V) on the long-period stacking ordered (LPSO) phase and the associated mechanical properties of ternary Mg-Er-Cu alloy were investigated. The addition of V has modified the morphology of 18R-type LPSO phase from coarse block-shaped into finer lamellar-shaped. The as-extruded Mg-Er-Cu (V) alloy presented more promising mechanical performance with the tensile stress of 430 MPa and apparent elongation of 11% at room temperature. Simple interpretation based on thermodynamics was also given.
