An estimate of the phase transition zone location in the flow section of the T-150-7.7 steam turbine operating as part of a 450 MW two-circuit combined cycle gas turbine unit during various modes of operation is provided. Stages were identified, in which stress corrosion cracking of the disks, as well as corrosion fatigue of the rotating blades are most likely to appear.
