摘要
磁性无损检测技术是评估铁磁材料疲劳损伤以及重要结构件可靠性的重要检测手段。针对铁磁材料的疲劳损伤,介绍了几种典型的磁性无损检测技术,如磁巴克豪森噪声(MBN)、磁声发射(MAE)、漏磁(MFL)和金属磁记忆(MMM)等,对其产生机理及应用特点进行了概述;对几种磁性检测技术在疲劳损伤评估领域的研究现状以及取得的主要研究成果进行了综述;最后指出几种技术尚存的问题和进一步的研究方向,并对其发展前景进行预测。
Magnetic non-destructive testing plays a significant role in evaluating the fatigue damage in ferromagnetic materials. Based on the fatigue damage in ferromagnetic materials, several typical magnetic NDT techniques, i. e. , magnetic Barkhausen noise （MBN）, magneto-acoustic emission （MAE）, magnetic flux leakage （MFL） and metal magnetic memory （MMM）, etc. , are introduced. The generation mechanism and application characteristics of those methods are overviewed. Meanwhile, the research status and main achievements of those methods are summarized. Finally the technical problems and further research directions are presented and the development prospect is also predicted.
