A novel Ni-free Zr-based bulk metallic glass with enhanced plasticity and good biocompatibility

A novel Ni-free bulk metallic glass (BMG) of Zr60Cu22.5Pd5Al7.5Nb5 was successfully prepared by copper mold casting. The BMG exhibited excellent mechanical properties, and superior corrosion resistance in an artificial body fluid and reasonably good biocompatibility, thus demonstrating its promise for biomedical application.
