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。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.
