Nondestructive evaluation of fatigue damage on low-alloy steel by magnetic technique
- Toshiba Corp., Yokohama (Japan)
In the nuclear power plant, fatigue damage is one of the most significant degradation behavior which is expected that the structural components is received during long term operation. In order to estimate the plant life and to ensure the reliability of the plants, nondestructive detection and evaluation of fatigue damage of the components are a key technology. Magneto mechanical acoustic emission (MAE) method was applied to the evaluation of fatigue damage of reactor pressure vessel steel. Several MAE parameters which were obtained from the signal processing and waveform analysis on fatigue specimens, were measured and investigated as a function of cumulative fatigue damage factor. Consequently, these MAE parameters were compared to the results by X-ray diffraction technique, hardness testing and microstructural observation. The usefulness of MAE method as the nondestructive evaluation technique of fatigue damage was discussed.
