... following the failure of the turbine rotor. The damage was maximum in the 18th/19th-stage seal land region of the compressor, with the 19th-stage blades sheared off. Metallurgical investigations were carried out on the roots and airfoil sections of the damaged blades. The blade roots had suffered excessive...
