Abstract Scope |
Beta titanium alloys are promising materials for load-bearing biomedical implants due to their excellent biocompatibility and low elastic modulus (~60 GPa). Combining these unique properties with the design freedom offered by additive manufacturing provides the opportunity to produce parts with tailored mechanical properties that best match those of the human cortical bone. In this work, we study a titanium niobium alloy produced via selective laser melting (SLM) using a mixture of pure elemental powders. We investigate the processing-structure-property space to identify a fully dense, low elastic modulus alloy design using a combination of scanning electron microscopy and mechanical testing. The large matrix of experiments we carry out offers the opportunity to study the origin of the different microstructures in detail and demonstrates the potential of microstructure control and design in beta Ti alloys through SLM. |
