An aging population worldwide with an extended lifespan is demanding more biomedical prosthetic devices, such as knee and hip replacements, to sustain an active lifestyle. Ti alloys are one of the best options for implant materials due to their biocompatibility and relatively low elastic modulus. A set of diffusion multiples for studying the Ti-Mo-Nb-Ta-Zr system are made and annealed at three different temperatures. Interdiffusion coefficients and impurity diffusivities are evaluated by performing a forward-simulation analysis of the electron probe micro-analysis (EPMA) data collected from the diffusion multiples. Elastic modulus is measured and mapped using nanoindentation technique. Foil samples are extracted in selected areas using focused ion beam (FIB) and investigated using transmission electron microscopy (TEM).
