alloys appear as attractive solutions to the aerospace industry because of their lightweight and cost-effectiveness. Complex structural parts can be manufactured to final shape without a need for machining and/or assembly operations. Nonetheless, the poor fatigue resistance properties exhibited by these materials, particularly in the high-cycle fatigue domain (HCF, 105
