| Abstract Scope |
Additive manufacturing of Ti alloys holds significant promise for orthopedic implants due to its advantages in customization, reduced processing time, and osseointegration. However, commercially available Ti alloy powders used in AM often contain bio-toxic elements such as V and Al, and consist predominantly of an α-Ti phase with a high modulus of elasticity. This high elastic modulus can lead to a stress-shielding effect, ultimately causing osteoporosis. Consequently, there is need to employ a biocompatible Ti alloy powder with exceptional biomechanical properties for additive manufacturing.
In this study, a biocompatible Ti-39Nb-6Zr alloy with a low elastic modulus was fabricated using VIGA-CC (Vacuum Induction Gas Atomization with Cold Crucible) and processed via selective laser melting process. Microstructural analysis was conducted using FE-SEM and EBSD, while mechanical properties were evaluated through compression tests and nanoindentation. |
