An integral blisk assembly includes a ceramic blisk having a forward and aft axial facing surface. To allow for torque transfer from the blisk, a forward and aft attachment ring contact the forward and aft axial facing surfaces respectively. These rings are mounted to other rotating components in the engine and are made of metal. A metal shim or precious metal coating may be disposed between the contacting surfaces to further reduce any stresses at the point of contact. To provide radial piloting, metal pilot rings are disposed underneath the regions where the attachment rings and blisk make contact. The aft attachment ring also has an axially extending base portion that in the event of a blisk failure contacts a stop that extends inwardly from the forward attachment ring, thereby preventing the other components in the engine from shifting.
