3-D growth of a short fatigue crack within a polycrystalline microstructure studied using combined diffraction and phase-contrast X-ray tomography

“…Hence, even small improvements in the material's behavior during this period can have a large impact on the overall lifetime. Since the pioneering work of Pearson [2] in the 1970s, numerous authors have studied the growth of short fatigue cracks (SFCs) in a large variety of metallic materials. This topic has been the subject of review papers and conferences [3][4][5].…”

“…Since the first observations of SFCs at the surface of Al fatigue samples by optical microscopy [2], more sophisticated techniques involving beach marking using ink [11] or change in environment [12], serial polishing [13], focused ion beam (FIB) milling [14] and synchrotron microtomography [15,16] have been used to study the relationship between local microstructure and the 3-D growth of SFCs. All these techniques have merits and disadvantages.…”
