摘　　要：06Cr17Ni12Mo2合金环锻件内部经超声波探伤发现有超标缺陷显示,缺陷将影响锻件性能,极易在精加工过程中暴露在成品表面,危害性极大。为了分析原因,利用低倍检验、金相显微镜、扫描电镜对06Cr17Ni12Mo2合金环锻件的探伤缺陷进行相关检测,确定缺陷形貌及性质,解剖的缺陷特征属于典型的Al-Si-O的化合物夹杂。Excessive defects were found in the inner part of 06Cr17Ni12Mo2 alloy ring forgings during ultrasonic flaw detection. The defects would affect the properties of the forgings. They were easily exposed to the surface of the finished product in finishing process, which was very harmful. In order to analyze the reasons, the defects in 06Cr17Ni12Mo2 alloy ring forgings were detected by means of macroscopic examination, metallographic microscope and scanning electron microscope. The morphology and characteristics of the defects were confirmed. It was found that tested defects belonged to the typical Al-Si-O compound inclusions.
