Overview of Surface Modification Strategies for Improving the Properties of Metastable Austenitic Stainless Steels

Metastable austenitic stainless steels (MASS) are widely used in various industrial applications due to their exceptional compromise between mechanical properties and corrosion resistance. However, the of these materials can be further enhanced by surface treatments. This paper reviews treatment methodologies improve MASS, with particular attention laser The effects treatments on microstructure chemical composition thermal affected zone MASS discussed, impact material’s properties, such as hardness, tensile strength, fatigue life, investigated detail. Additionally, highlights limitations points out some areas where research is needed. findings presented guide selection appropriate techniques for specific applications, ultimately improving performance lifespan settings.
