Advancing Structural Materials through Structure–Property Understanding
Department of Materials Science Engineering, Case Western Reserve University
(Host: Shulei Zhang)
Abstract: As energy efficiency and emission reduction become increasingly critical, the demand for structural materials and manufacturing methods capable of operating reliably at high temperatures in energy-generation and aerospace systems continues to grow. One promising approach is to tailor metal additive manufacturing processes to specific alloy systems, such as refractory alloys and steels, to optimize their performance and processability. This effort relies on an integrated understanding of thermomechanical processing, thermodynamic principles, and kinetic phenomena.
In this talk, I will present recent advancements in alloy design and additive manufacturing aimed at improving material performance under extreme conditions including high temperatures, cryogenic environments, energy systems, and lunar exploration missions. These developments are enabled by elucidating the composition–processing–structure–property relationships through multi-scale characterization of structural alloys.
Bio: Dr. Hyeji Im is an Assistant Professor in the Department of Materials Science and Engineering at Case Western Reserve University. Her current research focuses on the design and manufacturing of structural alloys to enhance industrial efficiency and promote environmental sustainability. This work involves tailoring the nano- and microstructures of metallic materials to achieve properties that surpass their intrinsic limits, including improved mechanical strength and oxidation resistance under extreme conditions. She received her Ph.D. in Materials Science and Engineering from Korea Advanced Institute of Science and Technology (KAIST) and continued her research as a postdoctoral fellow at Northwestern University.
