Abstract

The energy transition is growly rapidly. Yet, energy security and sustainability are still global concerns. The transition from fossil based, e.g., gas, to renewables, e.g., wind, hence, require reliable equipment and accurate lifetime predictions. Therefore, this review study is focused on turbine blades failures analysis with respect to their applications, materials, and operational conditions. Several cases relating the damage mechanisms associated with blades failures, e.g., corrosion-erosion, carbides precipitation, oxidation, coating degradation, high and low cycle fatigue, and creep, are discussed. To converge the topic, the work focuses on gas and wind turbine blades only. In addition, it sheds lights on several lifetime and failure prediction models and outlines recent trends in the additive manufacturing of turbine blades, e.g., core and microstructural grading. Lastly, it highlights several future research gaps that can aid in preventing similar failures.
