摘要：

The effect of thermal fatigue of steam generator pipe material on the Barkhausen noise is investigated by the acoustic emission method. Power, zero crossing rate, frequency characteristics, and the Hurst exponent were investigated in this analysis. As a result, it is found that the Hurst exponent is the most effective parameter to distinguish the progress of the fatigue.
