... Abstract A generating system in a hydroelectric power plant was shut down to investigate an abnormal sound coming from one of the turbines. A piece of metal that had broken off one of the vanes on the runner was found in the tail race and was subsequently examined along with the runner. Based...

... and corrosion resistance permitted turbine inlet temperatures up to 1200 °C (2200 °F) ( Ref 8 ). The first commercial application appeared during the late 1950s on cobalt-base first-stage turbine vanes. In the early to mid-1960s, this coating technology was applied to nickel-base superalloy turbine blades ( Ref...

... are exposed to the most demanding combinations of high temperature and stress. Wrought alloys have been used in the past for turbine blades and vanes in aircraft gas turbines. The approximate metal temperature range for airfoils of such alloys, when used, was about 1340 to about 1500 °F (about 727 to about...
