Measurement Tension Damage in Ferro-Magnetic Material by Using of Barkhausen Noise

摘要

In this paper, the change of Barkhausen Noise has been measured in the tension process of 09CuPTi steel. The relationship between Barkhausen Noise intensity and tension damage was obtained. The damage state of material and the change of damage in tension process can be shown by using of the intensity of Barkhausen Noise.
