抜粋

In order to clarify how the subsurface crack initiation site generates according to microstructure in high-cycle fatigue, Ti-6Al-4V alloys with different microstructures were subjected to fatigue test in liquid nitrogen. Microstructure influenced the S-N curves in long-life range. The subsurface crack initiation site was a facet or its aggregate which originated from the α grain transgranular cracking in each material. The size of subsurface crack initiation site highly depended on the maximum cyclic stress range.
