Abstract

The effect of Ag substitution for Cu on the glass forming ability (GFA) and mechanical properties of Mg₆₅ Cu_25-x Ag_xGd₁₀ (x = 0, 5, 10, 15, 20, 25) alloys were investigated using x-ray diffractometry and differential scanning calorimetry. The partial substitution of Cu by Ag in Mg₆₅ Cu₂₅Gd₁₀ promoted the GFA. Mg₆₅ Cu₂₀Ag₅Gd₁₀ bulk metallic glass (BMG) with a diameter of 11 mm could be fabricated by conventional copper-mold casting method in air atmosphere. The Mg₆₅Cu₂₀ Ag₅Gd₁₀ BMG exhibits yielding and plastic deformation during compressive loading. The compressive fracture strength, total strain to failure, and plastic strain to failure of the Mg₆₅Cu₂₀Ag₅Gd₁₀ BMG were 909 MPa, 2.21% and 0.5%, respectively.
