Innovative Approaches to Improve High-Temperature Mechanical Properties of Stainless Steels

Abstract

Stainless steels are extensively used in chemical, structural, and automotive sectors owing to their exceptional mechanical qualities at room temperature, resilience, resistance to corrosion, and affordability. Nevertheless, the inclination and increase in industrial requirements for components suitable for high temperatures, together with superior mechanical performance and resistance to corrosion, restrict their applicability in several scenarios and confine the criteria for their use. By manipulating the microstructure, altering the chemical properties, modifying the phase composition, and creating a compact three-dimensional network of dislocations, it is possible to customize and enhance the performance of stainless steels for challenging environments, such as high temperatures. Addresses the present emphasis on improving the mechanical characteristics of stainless steels at high temperatures. Despite their corrosion resistance, these alloys encounter challenges in maintaining mechanical integrity at elevated temperatures, affecting critical applications in various industries. The abstract provides an overview of multidimensional approaches, including alloy design, advanced processing, and innovative manufacturing, to tailor the microstructure and improve mechanical behavior at high temperatures. Surface engineering and computational modeling contribute to a comprehensive understanding. The interdisciplinary nature of this research reflects a dynamic landscape with promising advancements that could redefine the application of stainless steels in high-temperature environments.
