摘　　要：试验研究了 0 9Cu PTi (耐候钢 )在整个拉伸过程中巴克豪森噪声的变化 ,得到了巴克豪森噪声强度与拉伸塑性应变之间的关系 。The experiment measured the changes of Barkhausen Noise in the tensile process of 09CupTi steel and obtained the relationship between Barkhausen Noise intensity and tensile plastic sttain.Thus the damage state of the material and the changes of the damage during the process can be shown by way of the intensity of Barkhausen Noise.

关 键 词：巴克豪森噪声 材料损伤 无损检查
