Nickel base superalloys are used for turbine blades in gas turbine engines, and are required to
operate at very high temperatures (≈900°C) for long periods of time in an aggressive
environment. A particular problem is that although the operating times of such blades are
generally well-known, their effective operating temperatures are less well defined due to
variations in position and metal-gas temperature. The microstructure of this material is
known to evolve as a function of time and temperature. The aim of this research is to
develop a model that will enable the microstructure to act as a time temperature recorder for
IN738LC industrial gas turbine blades. [Continues.]
