外科植入物用Ti6Al7Nb和Ti13Nb13Zr合金组织与性能Microstructure and mechanical properties of Ti6Al7Nb and Ti14Nb13Zr alloys for surgical implants

在工业生产条件下，研究Ti6Al7Nb和Ti13Nb13Zr合金的组织、性能和生物相容性；并将Ti6Al7Nb、Ti13Nb13Zr合金与无毒对照组材料在动物体内、体外实验结果进行对比，评价了合金的生物相容性。结果表明：2种合金铸锭的化学成分及其棒、丝材组织与性能均满足GB 23102—2008、ISO 5832—11、ASTM F1295标准要求；生物学性能实验证明，合金不含毒性组元，生物相容性好，是理想的外科植入物材料；其中，Ti6Al7Nb合金的多种形式植入件的近百例临床使用表明疗效良好，适合临床应用。

Under the commercial run condition, the preparation technology, microstructure, mechanical properties, biological properties and clinical application of Ti6Al7Nb and Ti13Nb13ZrZr alloys were investigate. The results show that the chemical composition, microstructure and properties of bar and sheet meet the challenge of GB23102—2008, ISO5832—11 and ASTM F1295. The alloys possess nontoxic component and better biological compatibility. So, it is preferable surgical implant. The hundreds clinical experimental results show that Ti6Al7Nb has excessively curative effect.
