试验以20 ~ #钢和45 ~ #钢为研究对象,分别进行了含典型缺陷试件拉伸时表面泄漏磁场的在线测量和经过不同程度拉伸并卸载后表面泄漏磁场的测量。 - It shows that at the stress concentration zone , changes of mfl were relatively weak with slight deformation of the specimens . with the deforming to plastic and further the changing of mfl exhibits more distinct , and when necking emerging a very intensive change takes place . it is indicated that magnetic memory effect is related to the microstructure of the material
经分析认为,磁记忆信号的这种变化与材料内部微观组织的状态有关,试件变形很小时,磁弹性效应对试件表面泄漏磁场的变化起主要作用;试件变形较大时,其表面泄漏磁场的变化主要受塑性变形区内位错聚集产生的微缺陷的影响。
