Nondestructive materials characterization of irradiated nuclear pressure-vessel steel samples by the use of micromagnetic techniques and in terms of mechanical properties

Effects of Room Temperature Heavy-Ion Irradiation on Magnetic and Electrical Properties of a Single Crystalline Iron Thin Film

“…It has been reported that magnetic nondestructive evaluation (NDE) may be used to evaluate irradiation embrittlement of nuclear reactor vessels. [2][3][4][5] This application utilizes changes in magnetic properties because of the formation of irradiation defects. For neutron irradiation of bulk iron, magnetic hysteresis parameters increase by the formation of large dislocation loops.…”

Comparison of feature selection methods applied to Barkhausen noise data set

“…Mechanical properties are used usually to evaluate the fitness of the materials. These properties are typically measured destructively which cannot be obviously applied to the materials in use (Dobmann et al 2006). Thus, the evaluation is to be carried out with nondestructive methods.…”

Roadmap for Nondestructive Evaluation of Reactor Pressure Vessel Research and Development by the Light Water Reactor Sustainability Program

“…Studies have also shown that this technique is sensitive to damage precursors in ferromagnetic materials, and quantities such as the energy and peak value in the Barkhausen signal have been shown to correlate well with level of damage in materials [71][72][73][74][75]. Application of these methods to identify irradiation embrittlement has also been demonstrated to a limited extent in laboratory-scale studies [76][77][78], though the correlations identified are not always linear. This is generally due to the effect of multiple factors on the response.…”
