| Abstract Scope |
Metastable β-Ti alloys, particularly Ti-Nb systems, are widely recognized for biomedical applications due to their outstanding specific strength, corrosion resistance, biocompatibility, and low Young’s modulus. While extensive data exist for conventionally processed Ti-Nb alloys, studies on their fabrication via additive manufacturing, especially laser powder bed fusion (LPBF), remain limited. In this work, bio-compatible Ti-45 wt.% Nb alloys were fabricated with elemental feedstock powders using LPBF. Detailed characterization was conducted to investigate the local microstructure and phase evolution. To gain insight into the thermo-kinetic mechanisms governing microstructure development during L-PBF, a finite element-based thermal model was developed. This modeling approach enhanced the understanding of microstructural evolution and provided a systematic framework for optimizing process parameters. Additionally, the mechanical properties of the L-PBF-fabricated samples were evaluated to assess their suitability for biomedical applications. |
