Abstract

High-cycle fatigue properties were investigated for Ti-5A12.5Sn ELI and Ti-6A1-4V alloys (in the mill-annealed condition) at cryogenic temperatures. Subsurface crack initiation occurred in the long-life range for all alloys. The rolled materials of Ti-6A1-4V had much higher fatigue strength in the long-life range than the forged materials and the Ti-5A1-2.5Sn ELI alloy. The significant difference of fatigue strength in the long-life range for Ti-6A1-4V alloys was caused by morphological changes in their microstructure.
