摘　　要：用磁无损检测技术中的Ｂａｒｋｈａｕｓｅｎ杂讯法评估中碳钢的底周疲劳过程，表明Ｂａｒｋｈａｕｓｅｎ杂讯的幅值Ｂ随循环周次Ｎ的增长而变化，可以利用Ｂ和Ｎ的关系曲线来评估材料的损伤特性．Magnetic nondestructive evaluation technique, Barkhausen Noise methode were applied to evaluation of low cycly fatigue process in the medium carbon steel, and it was fond the RMS value of Barkhausen Noise B variated with the increases of cyclic loading numbers N. Using the curve which shows the relationship between B and N, the degree of fatigue damage can be estimated.

关 键 词：疲劳损伤 Barkhausen杂讯 中碳钢 磁无损检测
