Investigation on Mechanical Compatibility Matching for Biomedical Titanium Alloys
The effects of alloying elements such as Mo, Sn, Zr, Nb, deforming-rate, solid solution and aging treatment on mechanical property and microstructure of near βtype biomedical Ti alloys based on Ti-Nb-Zr system were studied. The Influential factors and their solution were discussed to keep matching of strength, elastic modulus, plasticity and toughness. Ti-Zr-Mo-Nb and Ti-Zr-Sn-Mo-Nb alloy systems possess excellent biocompatibility, lower elastic modulus, higher strength, finer plasticity and fracture toughness matching by means of solid solution and ageing treatment which are much more suitable for surgical implant and orthopedic materials.
