Precipitation Analysis of Nanoclusters in Lamellar Structured Titanium Alloy

  • 摘要: 以Ti-5Al-2Zr-1Sn-1Mo-1V合金为研究对象,发现其片层组织经950℃热处理后,局部区域出现α相的球化转变,而且经不同温度热处理后都有团簇物析出。应用聚焦离子束(FIB)微区精准取样,采用透射电镜对团簇析出物进行形貌观察和晶体结构衍射分析。结果表明,片层组织中的团簇析出物由多个尺寸不超过100 nm的Sn单晶颗粒聚集而成。
    Abstract: The α phase globularization is locally found in lamellar structure of Ti-5Al-2Zr-1Sn-1Mo-1V alloy after being treated at 950℃. Besides, clusters are found when the alloy is heat treated at different temperatures. The samples with clusters are accurately prepared by focused ion beam (FIB). The morphologies are observed and diffraction pattern is analyzed by TEM. The results show that nanoclusters in lamellar structure are composed of several Sn single crystal particles with the size of less than 100 nm.
