Abstract
A turbine bucket tip shroud is reinforced by introducing a reinforcing material such as a ceramic-matrix composite as reinforcing rods or bars into the casting of the tip shrouded turbine bucket, to provide resistance to creep deformation. By reducing creep deformation, unlatching of the interlocked tip shrouds is minimized, and bucket overload and vibratory failures are avoided.
