The longevity and performance of steam turbine components, which are essential assets in the infrastructure for power generation, are being greatly enhanced by advances in material science. This paper examines recent advancements made with the goal of using innovative materials and coatings to increase the longevity and effectiveness of turbine components. This review's scope includes an examination of cutting-edge materials, including composites, high-performance alloys, and ceramics, that are designed to endure the harsh conditions found in steam turbines. The effect that important developments in coating technologies—such as heat barrier and erosion-resistant coatings—have in reducing wear and improving operational reliability is addressed. The article emphasizes the integration of cutting-edge manufacturing processes including precision machining and additive manufacturing, which improve material properties and component performance, through a thorough study of the literature and industry practices. The review also covers methods for assessing material integrity in difficult operational conditions, with a focus on predictive modeling techniques and standardized testing procedures. The significance of these material developments for sustainable turbine operation and maintenance is highlighted by insights into their implications for the environment and the economy.
