摘要

We have discovered a new Cu-based bulk metallic glass (BMG). Although of a simple Cu₄₉Hf₄₂Al₉ ternary composition, the as-cast alloy is a monolithic, uniform BMG with a critical diameter as large as 10 mm. The width of the supercooled liquid region ΔT_x and the reduced glass transition temperature T_rg for this glass are 85 K and 0.62, respectively. In addition to its high glass-forming ability and high density of ∼11 g/cc, this BMG exhibits high ductility with a compressive plastic strain of 11-13%, making it a good candidate for applications as well as for studies of deformation behavior of Cu-based BMGs.
