摘要
声发射是一门正在发展中的新技术。由声发射信号的特征可关联到金属材料的塑性形变、断裂、相变 ,以及铁磁性金属材料的磁畴运动。由此阐述了声发射技术在材料科学的研究 ,金属构件与设备完整性动态检测 ,以及制造过程监控中越来越广泛的应用。
The characteristics of acoustic emission signals could be related with the metal material properties of plastic deformation,fracture and phase transformation as well as with the movement of magnetic domains in ferromagnetic metals.Acoustic emission technique is more and more widely applied into material research,dynamic testing of metal structure and equipment integrity,and monitoring in manufacturing procedure.
