... at the cooling hole surface could reach 1.3%, which is large enough to initiate the cracks. Creep relaxation is predicted to occur at the estimated temperature range of 705 to 730 °C (1300 to 1350 °F). The turbine start-stop cycles contribute to TMF stress cycling. Thus, the cracking at the cooling holes was due...
