Development of a Physically-Based Creep Model Incorporating Eta Phase Evolution for Nickel Base Superalloys
Nickel-base superalloys that are in service for long periods of time in fossil energy powerplants have microstructures that evolve with time. The strengthening gamma prime phase coarsens, and in some alloys, a new phase (eta) forms at grain boundaries, and its effect on creep performance is not fully understood.
