Abstract

A new Pd79Au1.5Ag3Si16.5 bulk metallic glass was successfully synthesized in a maximum casting thickness range to 3 mm. Upon heating, the single glassy phase decomposed into Pd-rich crystalline phases and a Si-rich amorphous phase due to solute partitioning. In addition to high thermal stability, this bulk glassy alloy also exhibited a high degree of ductility and excellent corrosion resistance, showing potential applications as biomaterials.
