摘　　要：某厂锻造的TC25钛合金盘类零件在交付前需进行水浸超声波探伤,合格后交付。但在交付后验收时进行X光射线探伤,发现其中一件零件的外轮缘部位有一处缺陷显示。因该缺陷用水浸超声波探伤未能及时检测出来,而X光射线探伤时却有效检测出来并对缺陷定位,对此问题开展研究。本文主要进行了模拟缺陷检出实验及能谱分析,确定缺陷的性质及特征。实验结果表明:X射线探伤检查对含钨金属夹杂物有效,属于高密夹杂,利用能谱分析夹杂物中心区域钨的成分接近100%。鉴于此种缺陷,对后续的TC25合金盘件交付状态更改为锻造+热处理(双重退火)+粗加工+X射线探伤,合格后再予以交付。The TC25 titanium alloy disc parts forged by a certain factory underwent water immersion ultrasonic testing and X-ray testing,and one of the parts showed a defect on the outer wheel edge,which was not detected by water immersion ultrasonic testing,but detected by X-ray testing.Research was conducted on this issue.Simulated defect detection experiments and energy spectrum analysis were carried out to determine the properties and characteristics of the defect.The experimental results showed that X-ray inspection was effective for tungsten inclusions.Energy spectrum analysis showed that the proportion of tungsten in the central area of the inclusion was close to 100 %.In view of this defect,the subsequent TC25 alloy discs need to undergo forging,heat treatment(double annealing),rough machining and X-ray inspection before delivery.
