Abstract: High strength, lightweight, low cost, and corrosion resistant alloys are needed to meet the current demand for increasing the fuel efficiency of vehicles, decreasing the carbon emission, and increasing the service life of engineering components. However, the development of the alloys with properties beyond conventional limits has been hindered by the limited understanding of the structure/processing/property/performance relationship at various length scales, lack of manufacturing technologies to engineer desired microstructure, and exploration of only a small compositional space. Ongoing work in the speaker’s lab has demonstrated possibilities of developing lightweight, high strength, and corrosion resistant metallic materials via a combination of suitable alloying elements and production/processing methods. A specific example of high strength and corrosion resistant Al alloys will be presented in this talk. Nanocrystalline Al-M (M: Cr, V, Mo, Ti, Ta, Nb, Ge, Y) alloys with extended solid solubility of the alloying elements have been produced in the speaker’s lab. The corrosion resistance and strength of the nanocrystalline Al-M alloys were superior to any commercial Al alloy. The role of nanocrystalline structure and extended solid solubility of the alloying elements on corrosion resistance was studied using X-ray photoelectron spectroscopy, transmission electron microscopy, and electrochemical methods. Ongoing efforts in extending the scientific understanding in producing bulk alloys and coatings for engineering applications will also be discussed.

Biography: Dr. Rajeev Gupta is an assistant professor in the Department of Chemical & Biomolecular Engineering at the University of Akron, Akron, Ohio. He earned the Ph.D. degree in Materials Engineering from Monash University, Australia, and B.Tech. in Materials & Metallurgical Engineering from the Indian Institute of Technology Kanpur. Prior to joining the University of Akron in November 2014, he was a research fellow at the Monash University, and then a research academic at the Deakin University, Australia. Rajeev’s primary research interests lie in the broad areas of corrosion and material engineering. His research group focuses on understanding the structure/processing/property relationships, corrosion initiation and propagation mechanisms, and high temperature oxidation. The fundamental research is intended to be applied in developing new alloys, corrosion monitoring techniques, and prediction of corrosion damage. Rajeev’s research has been continuously funded by the NSF, ONR, DOD, DOE, and industries. He has published 69 technical articles, which include 48 journal articles, one book, two book chapters, and 18 peer-reviewed conference papers. Rajeev is the inventor of 2 patents (pending). He has delivered several invited talks in various universities, industries, and conferences, including Aqueous Corrosion Gordon Research Conference 2018 and ECS annual meeting 2017.
