 note = {application/pdf, By using scanning electron microscope equipped with EDS and 3D analyses, microstructure and crack initiation site of a Ti-Fe-O alloy were characterized in order to clarify the internal fatigue crack generation. Most of fatigue samples failed at 77 K exhibited internal crack initiation, but pre-existing defects were not detected in the vicinity of initiation sites. The alloy consisted of recovered α grain and recrystallized α grain. The internal crack initiation site consisted of single or plural facets. Facet was transgranularly formed, and was fitted to a recrystallized α grain judging from its morphology, size, and chemistry.},
