| 摘 要： | 以燃气舵用钨渗铜（W-7Cu）为研究对象，通过观察和检测X射线探伤底片、金相组织、断口显微形貌及力学性能，对产品在X射线探伤过程中出现的条纹现象进行分析。结果表明，燃气舵用钨渗铜X射线探伤出现的条纹现象由材料的组织结构和工艺特点所决定，条纹区域的组织属于钨渗铜材料的正常组织，不存在孔洞、裂纹和渗铜不均等结构缺陷；产品条纹区域的性能指标满足技术要求，与材料无条纹区域的性能无显著差别；提出了对燃气舵用钨渗铜X射线探伤进行分级的建议。

| Abstract: | The stripe phenomenon of the tungsten infiltrated copper used in gas rudder (W-7Cu) during the X-ray flaw detection was analyzed by the observation and detection of the X-ray flaw detection negative, metallographic structure, fracture microstructure, and mechanical properties. The results show that, the stripe phenomenon during the X-ray flaw detection is caused by the structure and technological features of the tungsten infiltrated copper materials. The structure in the stripe region is the normal structure of the tungsten infiltrated copper materials without the structural defects of holes, cracks, and uneven infiltrated copper. The product properties in the stripe region meet the technical requirements, and there is no significant difference between the strip region and the non-striped region. The suggestion of grading the X-ray flaw detection for tungsten infiltrated copper used in gas rudder is proposed. |
