Abstract:

Mg-5Y-3Ni-0.2Zr (wt. %) and Mg-5Y-3Zn-0.2Zr (wt. %) alloys with LPSO structure have been designed and fabricated. The microstructure and mechanical property of both the extruded alloys have been comparatively studied. The results showed that the alloy with enough Ni exhibited higher elongation due to the high volume fraction of LPSO structure with excellent compatible deformation capability. The presence of deformation kinks with high kink angle demonstrated the capability of LPSO structure to accommodate the deformation, which could greatly increase the ductility and the toughness of the alloy.
