Study of cyclic strain localization and fatigue crack initiation using FIB technique
Original language description
Focused ion beam (FIB) technique together with other advanced microscopic techniques was applied to study the early microstructural changes leading to fatigue crack initiation in cyclically strained polycrystals. Dislocation structures of persistent slipbands (PSBs) and surrounding matrix were investigated in detail using electron channeling contrast imaging (ECCI) technique (simultaneously in the FIB cross-section and on the specimen surface) and transmission electron microscopy (TEM) of thin surfacefoils prepared by in situ lift-out technique. True shape of extrusions and intrusions and the path of initiated fatigue cracks were assessed in three dimensions by FIB micro-tomography. Advantageous potential and some limitations of FIB technique in fatigue crack initiation studies in polycrystals are highlighted.
