... housekeeping is thus mandatory in such plants to avoid service abnormalities. Abnormal temperature excursions in gas turbines result in creep deformation, cracking, and failure of nickel-base superalloy turbine blades. A peculiar failure of electric traction rails was reported in the early 1950s ( Ref...
