Non-destructive evaluation by VSM and CF of nanostructured materials [2022-2024]
The knowledge and mastery of NDT techniques through magnetic (VSM) and electromagnetic (CF) measurements allow scientists and industrialists to evaluate and control the structural state of nanostructured materials. In our research project, we are interested in the non-destructive evaluation of the structural state as well as the magnetic and electromagnetic behavior of nanostructured materials by: VSM through the analysis of hysteresis cycles, and eddy currents (FC) from the analysis of their impedance diagrams. This research work starts with VSM measurements to trace hysteresis cycles of nanostructured materials. All this leads us to determine magnetic parameters such as; coercivity, saturation magnetic moment, remanent moment, magnetic permeability, magnetic susceptibility, cycle area, IRM and first magnetization curve, in order to see the effect of external solicitations (mechanical milling, doping, traction...etc). Subsequently, we carry out CF checks to plot the impedance diagram in order to determine the following parameters such as; impedance, inductance, resistance, pulsed currents in the frequency range (20 Hz - 1 Mhz) with the aim of detecting surface defects of the different materials under study.
