It has been shown that this unique technique is efficient to reveal not onlythe fatigue dislocation structures in a large scale but also the relationship between the surfacedeformation bands and inside dislocation structures. It has been proven to be a powerful toolto connect macrostructures and microstructures in fatigued materials.
