Abstract Advanced air-cooling turbine blades are capable of operating above the melting temperature of Nickel-based
superalloy, which accordingly withstand complex thermomechanical fatigue loads during service life. This
paper considers the problem of realizing gas turbine representative thermal gradients in the elevated
temperature fatigue test, while ensuring the thermal gradient induced stress inside the specimens. For this
purpose, a novel temperature control device utilizing impingement cooling, which supplies cooling air inside
the gauge section and releases toward the inner wall, was constructed in tubular fatigue specimens. A single
induction coil was arranged outside the gauge section, providing heat sources to establish thermal… More >
