Title: High Strength-High Toughness Alloys for 21st Century Design Challenges
As other technologies advance at breakneck pace, metallurgical science is quickly becoming one of the primary limiting factors for performance of many modem systems. The U.S. Navy and other entities (e.g. the other defense branches and the commercial nuclear and shipbuilding industries) often rely on decades-old steels and nonferrous alloys to cope with operating environments that induce dynamic loading, corrosion, high temperatures, and fatigue. Demand for new, high-performance alloys is driving a push to perform agile development of new steels and corrosion-resistant alloys to enable platform capability. This creates an interesting dichotomy: while the next century's extreme environments are almost unimaginable to the metallurgists of the 1950s, so are the computational, characterization, and manufacturing tools that are available to metallurgists now.
During this presentation, Dr. Schwarm will discuss work performed within the Navy using holistic approaches for designing alloys for long-term use in highly demanding environments. These approaches include not only mechanistic understanding of how to improve performance parameters, but also feature computational design via Integrated Computational Materials Engineering (ICME), design for manufacturing scale-up and fabrication, and design for manufacturing by non-traditional methods (i.e. additive manufacturing). Ultimately, next generation structural metals are going to need to outperform current alloys in many different performance metrics without sacrificing weight, manufacturability, or cost. These goals are achievable using modem materials science capabilities to innovate metallurgical approaches into the future.
Dr. Schwarm is a metallurgy subject matter expert (SME) at the Naval Surface Warfare Center - Carderock Division in Bethesda, MD, where he performs applied materials research for the U.S. Navy submarine and surface fleets. Having earned MS and PhD degrees from the University of Maryland (MSE Dept), he performed his dissertation research on nuclear structural materials as a Department of Energy Nuclear Energy University Programs (DOE-NEUP) fellow. Prior to these roles, Dr. Schwarm earned a BS in Metallurgical Engineering from the University of Alabama.
