About

Timothy Weihs is a professor of materials science and engineering at Johns Hopkins University, with a focus on the fabrication, characterization, and application of reactive, structural, and biodegradable materials. His research aims to understand how novel processing techniques and chemistries can produce unique microstructures and properties for scientific studies and specific applications. Weihs has developed sputter-deposited reactive multilayer foils as model materials for studying phase transformations and as local heat sources for soldering and brazing components. He co-founded Reactive NanoTechnologies to commercialize these foils and served as its CEO until 2009. His work extends into energetic materials, including reactive metal powders and structural energetic materials for bio and chemical agent defeat. Weihs directs the Materials Science in Extreme Environments University Research Alliance (MSEE), which sponsors related research. His group fabricates powders through ball-milling, ultrasonic atomization, and sputter deposition to enhance ignition and combustion properties. In structural materials, he has refined the microstructure of FeCo alloys for jet engine applications and Mg alloys for armor applications. Currently, his research involves working with Professor Falk to explore dislocations and vacancies in Mg and Al alloys, and within the Center on Artificial Intelligence for Materials in Extreme Environments (CAIMEE) to develop novel metallic alloys.
