Distinct Plasticity of Biocompatible Ti-Zr-Cu-Pd-Sn Bulk Metallic Glass
(English)Manuscript (preprint) (Other academic)
We have developed Ti-Zr-Cu-Pd-Sn bulk metallic glass without toxic elements which exhibits distinct plasticity (~12.6%) by revealing strain hardening before failure. Specimens performed under compression tests do not show any crystalline phases which usually enhance plasticity by branching or restricting the rapid propagation of shear bands. Along with excellent mechanical properties alloy exhibits appreciably high bulk forming ability, GFA, with large supercooled regime (~56K) and as a consequence cylindrical rods of at least 7mm were fabricated directly by Cu-mold casting. The combination of such mechanical properties and appreciably high bulk forming ability makes it a potential candidate for biomedical applications.
