Towards Sustainable Alloys: Overcoming Corrosion Challenges by Engineering Suitable Microstructures

Rajeev Gupta, Department of Materials Science and Engineering, North Carolina State University, NC, USA

Abstract

Reducing material consumption, increasing the useful service life, and promoting recycling are critical components of creating a sustainable future. Corrosion reduces the useful life of engineering components, necessitating the production of more materials. Additionally, corrosion-resistant metallic materials are often heavier, resulting in higher carbon footprints. As a result, the need to develop lightweight, high-strength, and corrosion-resistant materials is steadily increasing. The properties of engineering alloys are often limited by conventional compositions and manufacturing technologies. The speaker's recent work has demonstrated the development of alloys with properties that exceed traditional limits, achieved through precise control of microstructure and composition. Specific examples of high-energy ball-milled alloys and additively manufactured alloys will be presented, showing how high corrosion resistance can be achieved through the design of unique microstructures.
