    via synchrotron radiation X-ray computed tomography

## Description

- description: The initiation of internal fatigue cracks in very high cycle fatigue
    of Ti-6Al-4V alloy was investigated using synchrotron radiation X-ray computed
    tomography (SR-CT). Micro-CT detected 28 cracks that were distributed across the
    examined volume of Ф1.8 × L 2.5 mm. No apparent correlation was observed between
    the spatial distribution, initial lengths, and initiation lives of cracks. The
    crack growth rate of the facet-sized crack varied widely; some cracks propagated
    rapidly, whereas no crack growth was observed for other cracks over a specific
    period of time after detection. Using nano-CT, the several grain-sized internal
    cracks and their microstructures were clearly and nondestructively visualized.
    In the field of view, many primary α phases were detected; however, no other cracks
    were observed. The multiple facet initiation site, which is commonly observed
    for titanium alloys, might not be due to the concurrently initiated facets but
    may be caused by the small crack growth accompanied by facet formation.
