| Abstract Scope |
Titanium-Niobium (Ti-Nb) is one of the promising beta-type titanium shape memory alloys for biomechanical applications. Due to their metastable nature, these alloys can be tailored via thermo-mechanical processing to have a modulus from 30-110 GPa based on our recent findings. By applying additive manufacturing methods, these alloys can be further customized to create regional differences in the mechanical properties of a part. By applying different scan strategies and processing parameters at the different regions, we observe a material with location-varying mechanical properties – for example, differences in the local stiffness. This manufacturing method provides an additional degree of freedom in material design and will be useful for the applications such as biomedical implants which require multiple different properties within the same part but is often limited in part geometry and number of materials used. |
