摘要(Abstract)：

利用X射线衍射(XRD)、扫描电镜(SEM)、透射电镜(TEM)、纳米压痕以及电化学测试等研究了时效温度对Ti-35Nb-5Ta-7Zr合金α相的数量、尺寸与分布特征以及力学性能和腐蚀行为的影响。结果表明：在400～450℃时效处理后，大量针状α相优先在晶界位置析出，并随温度升高呈网状结构；在超过500℃时效处理后，α相进一步长大，呈三角特征且分布均匀。合金的强度与弹性模量随时效温度升高呈现先升高再降低的趋势，在450℃时达到峰值，断后伸长率随时效温度升高逐渐提高。由此可见，合金强度、塑性与弹性模量随时效温度的变化与α相数量、尺寸和分布特征密切相关。随着时效温度的升高，Ti-35Nb-5Ta-7Zr合金在模拟体液中的耐蚀性呈现先降低后升高的趋势。分析可知，400～450℃时效时，富Ti而少Nb、Zr的针状α相在晶界与晶内析出，因其与基体存在电位差形成原电池，故针状α相数量增加导致耐蚀性降低；时效温度超过500℃时，α相在晶界与晶内均匀析出，降低了局部腐蚀倾向，促进均匀钝化膜的形成而提升耐蚀性。
