0〉-orientation-dependent crack initiation in a titanium alloy under dwell fatigue
Soft grains with a “rotation angle” between 15° and 30° are prone to induce cracking in hard grains, for the reason that prismatic dislocation slips in these soft grains exert a higher stress (higher κ value) normal to the basal plane of hard grains.
