摘要
In the present study,high-zirconium ternary Zr-Al-Fe bulk metallic glasses(BMGs) with low Young's modulus and good plasticity were developed.Zr75 Al7.5 Fe17.5 BMG exhibits a low Young's modulus of 70 GPa and high Poisson's ratio of 0.403.Pronounced 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 properties implies potential for biomedical applications.

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.
