Using the methods of electric arc melting, intermediate heat treatments, and consecutive intensive plastic deformation, a Ti-Nb-Zr alloy wire with a diameter of 1200 μm was obtained with a homogeneous chemical and phase (β-Ti body-centered crystal lattice) composition corresponding to the presence of superelasticity and shape memory effect, corrosion resistance and biocompatibility. Perhaps the wire structure is represented by grains with a nanoscale diameter. For the wire obtained after stabilizing annealing, the proof strength Rp0.2 is 635 MPa, tensile strength is 840 MPa and Young's modulus is 22 GPa, relative elongation is 6.76%. No toxicity was detected. The resulting wire is considered to be promising for medical use.
采用电弧熔炼、中间热处理和连续强烈塑性变形的方法，获得了直径为1200μm的Ti-Nb-Zr合金丝，其具有均匀的化学和相（β-Ti体心晶格）组成，表现出超弹性和形状记忆效应、耐腐蚀性和生物相容性。该丝的结构可能由纳米级直径的晶粒组成。对于稳定化退火后得到的丝，其规定非比例延伸强度Rp0.2为635MPa，抗拉强度为840MPa，杨氏模量为22GPa，相对伸长率为6.76%。未检测到毒性。所得的丝被认为具有医疗应用前景。
