| Abstract Scope |
Large Ti-64 forgings can exhibit a High Cycle Fatigue life debit compared to plate or bar at high lives (N=1E8) associated with dwell-like faceted subsurface initiation. Forgings can also exhibit greater mean stress sensitivity, especially in notched fatigue. Here we examine the effect of placing the notch root in hard/soft macrozone combinations found in EBSD under R=0.5 HCF conditions and the associated initiation features and dislocations observed on subsequent SEM and TEM examination. |
