| Research Abstract |
The previously developed bulk metallic glasses (BMGs)with their critical glass-formation diameter exceeding 1 cm contain toxic elements such as Ni and Cu, which has restricted the application of BMGs as biomedical application. The present work has successfully prepared Cu and Ni-free Zr-based BMG with the critical glass formation diameter of about 2 cm. We have also developed a novel method of selective removal of toxic elements and simultaneous formation of porous structure on the surface of the BMGs by using dealloying phenomenon in the metallic melt.
