This paper presents the evaluation of heat transfer rate on the surface of turbine moving blades based on their microstructural changes due to aging. γ' strengthen nickel base superalloy are used extensively in turbine moving blades. The aging effect on the change of γ' precipitates is investigated. The average diameter of γ' precipitates increases linearly with time raised to the one-third power for aging temperature. The metal temperature of turbine moving blades used in gas turbine field operations could be estimated by applying the above method. Also, its temperature is obtained numerically from the heat transfer rates which are calculated using some analytical methods. By comparison of both metal temperatures, the heat transfer rates on the surfaces of turbine moving blades used in gas turbine field operations are estimated and are evaluated.
