针对聚变装置高热流部件热沉用ITER(国际热核聚变试验堆等级)CuCrZr合金冷拔薄壁管近表面折叠缺陷,采用光学显微镜和扫描电子显微镜观察分析了此类折叠缺陷的产生原因,并运用超声底波衰减法实现了对此类缺陷的无损检测,超声仿真模拟也证实了该检测方法的可靠性。结果表明:目视和涡流方法对检测聚变装置热沉用CuCrZr合金管的检测并不完善,为了确保管材的质量还需增加超声波检测方法。
Aiming at the heat sinking of high heat flux component of fusion device, the causes of folding defects of cold-drawn thin-walled tubes of ITER (ITER) CuCrZr alloy were observed and analyzed by optical microscope and scanning electron microscope The non-destructive testing of such defects is realized by using the ultrasonic bottom attenuation method. The ultrasonic simulation also confirms the reliability of the detection method. The results show that the visual and eddy current methods are not perfect for the detection of CuCrZr alloy tube for heat sink of fusion device. In order to ensure the quality of the tube, ultrasonic testing method is needed.
