Reconditioning of gas turbine components by heat treatment

At the high operating temperatures experienced within a gas turbine, creep damage is a major life-limiting factor. This is especially true for compone nts which are highly stressed and closest to the hat gas inlet end of the m achine, such as the rotating blades in this area. The ability to recover th e creep properties of used gas turbine components might enable their servic e lives to be increased consider-ably. Thereby, maintenance costs could hea t treatment will be reviewed and perceived limitations identified. The curr ent work will be reduced. Previous research into the feasibility of recondi tioning crept superalloys by add to knowledge on the effects of conventiona l recovery techniques and will explore potential new heat treatment regimes . The experimental and analytical methods to be used will be both described and supported by preliminary results.
