The Department of Mechanical, Materials, and Aerospace Engineering presents the 2023–2024 seminar series featuring guest speaker, Matthew Daly, who will give a presentation on “Deformation Mechanisms at the Mesoscale: From 2D Materials to High Entropy Alloys.” This seminar will take place on Wednesday, November 1, 2023 in the auditorium (room 104) of the John T. Rettaliata Engineering Center from 3:30–4:30 p.m. This event is open to all graduate students and faculty.

Abstract

Despite considerable progress in the scientific understanding of deformation processes, the mechanical properties of engineered materials remain limited to fractions of their theoretical values. A significant barrier to further breakthroughs in mechanical property enhancements is the challenge of scaling. Specifically, while materials often exhibit near-theoretical properties at the nanoscale, preserving these exceptional characteristics in the bulk remains a pervasive challenge. In response to this issue, my group focuses on examining deformation processes at the mesoscale. At this intermediate scale, much remains unknown about how nanoscale defect behaviors aggregate and transition into the emergent bulk mechanical properties. Our efforts are supported by a complementary blend of experimental and computational techniques, such as small-scale in situ mechanical testing and targeted simulations. This suite of tools is specifically designed to capture the essential physics of deformation processes and then relay that information across the relevant length scales of microstructure. This emphasis on scaling rules and the aggregate effects of deformation processes underpins the broader objective of my work, which is to develop materials systems that overcome traditional strength-ductility trade-offs. In this seminar, I will present case studies under this theme in 2D materials, high entropy alloys, and time permitting, new efforts in metal additive manufacturing.

Matthew Daly is currently an assistant professor of materials engineering at the University of Illinois Chicago (UIC). Prior to this appointment, he completed his postdoctoral work at Northwestern University through a fellowship from the Natural Sciences and Engineering Research Council of Canada. He received his Ph.D. in materials science and engineering from the University of Toronto in 2017, and his bachelor’s and master’s degrees in mechanical engineering from the University of Waterloo. His research interests include: the mechanics of nanostructured materials; advanced materials and microstructure design; in situ characterization techniques; mechanical metallurgy; and atomistic modeling. Daly earned the Governor General of Canada Gold Medal for his research in 2012, and more recently is the recipient of a 2022 National Science Foundation CAREER Award. He is an active member of the Minerals, Metals, and Materials (TMS) and the Society for Standardization Professionals (SES) professional societies. With TMS he is the recipient of the 2023 Young Leaders Professional Development Award. Additionally, he has won several awards for his teaching at UIC, such as the Edmund Burke Faculty Award for teaching excellence in 2019 and the UIC College of Engineering Teaching Award in 2022.
