Abstract

New Mg-based amorphous alloys with high strength and good ductility were produced in the Mg-Ce-Ni system by melt spinning. The tensile fracture strength ( σ f ) and Vickers hardness reach 750 MPa and 199 DPN for Mg 80 Ce 10 Ni 10 . The specific strength defined by the ratio of σ f to density is as high as 27, being considerably higher than the highest value (≃20) for conventional Al-based alloys. The high-strength Mg-base amorphous alloys are expected to attract much attention as a new type of high-strength material with low density.
