中文摘要	Fatigue properties of Ti alloy thin foils only containing a single colony in the through-thickness direction were investigated by bending fatigue tests. It was found that fatigue strength of the micron-thick foil in the high-cycle fatigue regime was higher than that of its bulk counterpart, while that was in inverse in the low-cycle fatigue regime. Such a difference in fatigue resistance was elucidated based on microscopic observations on fatigue damage behaviors. The present study clearly demonstrates that fatigue properties of the Ti alloy thin foil become more sensitive to microstructures than its counterpart as the geometrical scale of the material being comparable to the microstructure scale.
