Abstract
Gas turbines for aeroengines are generally manufactured by attaching individual blades into slots in the disk. However, an alternative design consists in producing bladed disks, where disk and blades are a single piece. Previous studies have shown that linear friction welding is a technology which fits well for this application. On the other hand, bladed disks can experience in service damages and therefore affordable repair technology must be available. The present paper presents the microstruc...
