| Outline of Final Research Achievements |
In this study, an evaluation system using an inherent magnetic senor based on a work-affected layer, generated on a metal surface during production process, for the evaluation of fatigue deterioration in stainless steel was developed.
The factors determining the magnetic properties of the inherent magnetic senor, the relationship between the magnetic properties and tensile stress, and the relationship between magnetic properties and tensile cyclic deformation were demonstrated by experiments and through analysis. Finally, the increase in the number of cycles from zero cycles was monitored by measuring the change of magnetic properties in the work-affected layer during the plane bending fatigue test.
