| Abstract Scope |
Along with practical feedbacks during the past decades, some limits raised in the use of classical TA6V-ELI alloy for biomedical applications. In reaction, this work brings a contribution to the design and characterization of metastable â titanium alloys, with respect to biocompatibility. The potential of Ti-Mo based alloys for biomedical applications has been widely promoted. Thus, Ti-Mo-Zr-Sn quaternary alloys have been designed using the « d-electron method », with regard to corrosion resistance (Zr addition) and the embrittlement due to athermal-ω (avoided with Sn addition). The alloys were obtained by arc melting and were then subjected to thermomechanical treatments so that their microstructures were optimize. In addition, tensile tests were conducted in order to assess their mechanical properties according to their chemical compositions. Further research work consisted in investigating the deformation mechanisms using EBSD, in order to check the reliability of the « d-electron method » for the design of TWIP/TRIP metastable β titanium alloys |
