摘　　要：简要介绍了航空用Ti-3Al-2.5V钛合金管材从研制到应用的全过程,确立了管材制备过程中挤压、轧制、热处理等关键工艺过程及其参数,建立了管材的组织与性能各向异性评价新参数CSR,为管材的科学评价提供了保证,提出了钛合金管路连接技术的现状及发展趋势。这些工作为我国研制和应用Ti-3Al-2.5V管材提供了重要的方法与思路。The manufacturing process, properties and application of Ti-3Al-2.5V alloy tubes are introduced briefly. Manufacturing techniques such as extrusion, rolling and heat treatment, etc, and critical process parameters are established. A new parameter CSR for microstrcture-property anisotropy evaluation is put forward, which guaranted the scientific appraisal of the tubes. The current status and development trend of titanium alloy pipeline connection technique are discussed. Those works provide important foundation for the development and application of Ti-3Al-2.5V alloy tube in our country.
