Abstract

The objective of this work is to create a new class of porous metallic implant materials combining the biocompatibility of pure titanium with the superelasticity of Nitinol. Ti-20.8Nb-5.5Zr, Ti-22Nb-6Ta (at%) and Ti-CP foams are produced by the spaceholder technique and characterized from both the pore morphology and the mechanical behavior points of view. To support these developments, a multi-scale representative volume element-based approach is proposed and experimentally validated. Using this approach, the implant’s porosity can be engineered, and the base material properties adjusted, so that the implant could offer adequate pore morphology for bone ingrowth while offering high mechanical resistance.
