Summary I am conducting research into nondestructive evaluation methods using relationship between lattice defects and magnetism at the Non-Destructive Evaluation and Science Research Center. More specifically, my research is focused on finding correlations between magnetism and neutron irradiation embrittlement with the aim of applying the results to evaluation of the remaining life of reactor pressure vessels in nuclear power plants; validating analytical methods for magnetic minor hysteresis loops, which are effective for nondestructive evaluation from the viewpoint of low measurement field and high sensitivity to defect density; and verifying the efficacy of magnetic nondestructive evaluation methods for age deterioration of non-magnetic austenitic stainless steel using the strain-induced ferromagnetic martensite phase.
Research Fields Magnetism, Metal Physics, Magnetic Non-destructive Evaluation
