implementation of the modified Ti-based shape memory alloys, it has been reported that Ti-Nb [7, 8], Ti-Mo [9, 10] and Ti-V [11] alloys can induce shape memory effect. However, in Ti-Nb, low shape recovery...-Ta shows more excellent corrosion resistance and biocompatibility than other percentages, obtaining almost the same behaviour of the pure Ti and Ti-6Al-4V alloys, which can be recommended......
