Abstract Scope |
Magnesium-based metallic glasses are well-known for their low density, high specific strength and potential as resorbable biological implant materials. In this study a range of magnesium-rich (85-87 atomic percent) metallic glasses are developed from the Mg–Pd–Ca and Mg–Pd–Yb alloy systems. A solvent-rich amorphous alloy design method and properties of these amorphous alloys shall be presented. It is found that alloys within the composition range Mg86.4-87Pd7-7.7Ca5.8-6 and Mg86.4-87Pd7-7.7Yb5.8-6 are completely amorphous when copper mould-cast in sections ≥1mm diameter. These alloys exhibit hardness of 2.7-3.2 GPa, Young’s modulus of 62-64 GPa and density of 2.15-2.35 g/cm3 for Ca- and 2.81-2.96 g/cm3 for Yb-containing glasses. |
