Biocompatible Zr-Al-Fe bulk metallic glasses with large plasticity

In the present study, high-zirconium ternary Zr-Al-Fe bulk metallic glasses （BMGs） with low Young＇s modulus and good plas- ticity were developed. Zr75Al7.5Fe17.5 BMG exhibits a low Young＇s modulus of 70 GPa and high Poisson＇s ratio of 0.403. Pro- nounced plasticity was demonstrated under both compre...

Description
Summary:In the present study, high-zirconium ternary Zr-Al-Fe bulk metallic glasses （BMGs） with low Young＇s modulus and good plas- ticity were developed. Zr75Al7.5Fe17.5 BMG exhibits a low Young＇s modulus of 70 GPa and high Poisson＇s ratio of 0.403. Pro- nounced plasticity was demonstrated under both compression and bending conditions for the BMGs. Furthermore, the alloys show high corrosion resistance in phosphate buffered solution. The combination of desirable mechanical and chemical proper- ties implies potential for biomedical applications.
