Lifecycle costs and the performance of gas turbines depend on selecting the best materials for them. The main reason for proper maintenance in gas turbines is the quality of the material. The operation of gas turbines ends up with gas path degradation, and in the next step, life cycle costs, design, manufacture materials, and maintenance […]

The maintenance of the gas turbine blades is important because these blades are operated in harsh conditions. Therefore, nickel-based superalloys that offer excellent performances in high-temperature conditions are typically used, and the blades are inspected and replaced based on the manufacturer’s maintenance standards. However, the service life can be extended by refurbishing the blades that […]

Thermal fatigue is a fatigue failure with macroscopic cracks resulting from cyclic thermal stresses and strains due to temperature changes, spatial temperature gradients, and high temperatures under constrained thermal deformation. Thermal fatigue may occur without mechanical loads. The constraints include external ones (e.g., bolting load) and internal ones (e.g., temperature gradient, different thermal expansion due […]
