Notched Fatigue and Fretting Fatigue Life of Textured Titanium.

Abstract

The effect of texture, (0002) poles in the transverse direction, on the notched and fretting fatigue life of a Ti-4Al-4V alloy was examined. Notched fatigue and pin-loaded flat fretting fatigue specimens were tested at room temperature in the longitudinal and transverse directions and compared to smooth bar fatigue results. Fractured fretting fatigue specimens were examined with the scanning electron microscope. Indications are that no fretting or notch fatigue anisotropy exists for the transverse type texture and specimen orientations examined. However, as expected, a significant reduction of the fatigue life is displayed for specimens subjected to fretting fatigue. (Author)
