The objective of this research is to develop novelβ-Ti base superelastic alloys composed of biocompatible alloying elements. The effects of alloying elements on transformation temperature, crystal structure and mechanical properties of Ti-Zr-Nb-(O,N) alloys were systematically investigated. As a result, the alloy design principle for Ti-Zr base superelastic alloys with a large recovery strain and high superelastic stress was established. The effect of thermomechanical conditions on microstructure and mechanical properties was also investigated, and the optimum thermomechanical condition for each alloy was established.
