“…[1][2][3] In addition, it has been reported that some Ti-Nb base alloys, such as Ti-(26-27) at.%Nb, 4,5 Ti-Nb-Sn, 6 Ti-Nb-Zr, 7 Ti-Nb-Ta, 8 exhibited superelasticity at room temperature. The superelastic recovery strains of these alloys are small compared with Ti-Ni superelastic alloys mainly due to the low critical stress for slip and small transformation strain.…”
