This communication describes the results of spectrum fatigue loading experiments conducted on castHIT Ti-6Al-4V. the purpose of the experiments is to elucidate the nature of the faceted crack growth that occurs at low values of delta-K in titanium alloys and also other alloys. The results clearly show that thousands of load cycles are required for the crack to grow across a single facet. The confusing terminology relating to low delta-K fatigue fracture topography is reviewed and the term low delta-K faceted growth is proposed as a descriptor.
