中文摘要：以某航空发动机钛合金叶片为研究对象，采用光学金相（OM）和EBSD等技术对叶片流线和非流线区域的显微组织、位向分布及显微硬度等参数进行了对比分析，揭示了叶片流线的性质和成因，对钛合金叶片工程应用具有重要的参考价值。
英文摘要：Based on optical microscopy (OM) and EBSD, the titanium alloy blades of aero-engine compressor were studied. The microstructure in the regions of blade flow line / non-flow-line, distribution and micro-hardness were comparatively analyzed. The character and causes of blade flow line of the titanium alloy were revealed, which was significant to the engineering application of titanium alloy blades.
