Topic: Towards Sustainable Alloys: Overcoming Corrosion Challenges by Engineering Suitable Microstructures 

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.

Bio:

Rajeev Gupta is an Associate Professor of Materials Science and Engineering at North Carolina State University. He received B.Tech. in Materials and Metallurgical Engineering from Indian Institute of Technology Kanpur and Ph.D. in Materials Engineering from Monash University. Before joining the faculty at NC State, he was an Assistant Professor at the University of Akron.

Rajeev’s primary research interests lie in the broad areas of corrosion and materials engineering. His research group focuses on corrosion science, understanding the structure–processing–property–performance relationships in metallic materials, and surface electrochemistry. This fundamental research aims to support the development of new materials, corrosion characterization techniques, material processing technologies, and life prediction models. His research is supported by the NSF, DOD, DOE, ONR, and industries. Rajeev serves as an Associate Editor of the Journal of the Electrochemical Society and is the recipient of the NSF CAREER Award, ECS Rusty Award for Mid-Career Excellence, AMPP Educator Award in honor of Herbert Uhlig, and ACA Brian Cherry Award.
