通过超声检测对钛合金材料内部的可疑缺陷进行定位，采用低倍检验、高倍检验以及微区化学成分能谱分析等方法对缺陷部位进行分析，并将分析结果与超声检测结果进行比较。结果表明：超声检测技术能够有效检测发现钛合金材料内部的夹杂、孔洞、过热组织（局部组织粗大、组织不均匀）等缺陷，而对于低倍检验中发现的局部化学成分偏析类缺陷则不能有效检测出，同时异常的内部组织也会影响到超声检测的正常判别。

The suspicious defects in titanium alloy materials were located by ultrasonic detection. The defects were analyzed by means of low magnification test, high magnification test and energy spectrum analysis of micro-area chemical composition. The results were compared with those of ultrasonic detection. The results show that the ultrasonic detection technology could effectively detected the inclusions, holes, superheat structure (local coarse, uneven structure) and other defects in the titanium alloy materials. However, the local chemical segregation defects found in the low magnification test could not be effectively detected by ultrasonic detection, and the abnormal internal structure will also affect the normal discrimination of ultrasonic detection.
