| Abstract | A fatigue level estimation method includes estimating a fatigue portion in a metal material, measuring a distribution of a misorientation in the fatigue portion, obtaining a specific area ratio of the fatigue portion based on the distribution of the misorientation in the fatigue portion, and obtaining an estimated fatigue level of the metal material based on at least one of the specific area ratio of the fatigue portion and a degree of change in the specific area ratio of the fatigue portion. The specific area ratio of the fatigue portion is a ratio of a specific area existing in a measurement area of the fatigue portion. |
