Fabrication and Mechanical Properties of Mg₆₅Cu₁₅Ag₅Pd₅Gd₁₀ Bulk Metallic Glass

抄録

The effect of partial substitution of Cu for Ag and Pd on the glass forming ability of Mg₆₅Cu₂₅Gd₁₀ alloy has been studied. Mg₆₅Cu₁₅Ag₅Pd₅Gd₁₀ bulk metallic glass with diameter of at least 10 mm can successfully be fabricated by conventional Cu-mold casting method in air atmosphere. The critical cooling rate for glass formation is estimated to be ∼0.7 K/s. The compressive fracture strength and fracture elongation of the Mg₆₅Cu₁₅Ag₅Pd₅Gd₁₀ bulk metallic glass are 817 MPa and 1.6% respectively.
