摘要
针对航空航天关键件所使用的2A14-T6铝合金锻件内部可能存在的不可预知的缺陷,开展基于超声相控阵技术的检测工艺及方法研究。通过合理布置相控阵探头的位置,选用合适的相控阵探头和扫查方式,试验发现超声相控阵检测技术可以对满足Φ2 mm当量的不同类型缺陷的检出。与常规超声检测方法相比,超声相控阵技术检测铝合金锻件有着更大的技术优势和应用前景。
As unpredictable defects may exist in the 2Al4-T6 aluminum forgings used for aerospace key pieces, research has been done on the defect detecting technology and methods based on the ultrasonic phased array technology. The test result shows that the ultrasonic phased array technology can be used to detect different types of defects equivalent to φ2 ram,if the phased array probes are selected and arranged appropriately with the adequate scanning mode. Compared with the conventional ultrasonic testing methods, there is a greater technological advantage and a brighter application future as the ultrasonic phased array tech- nology is used to detect aluminum forgings.
