While all of our projects involve materials, the focus of some is engineering better materials. We have two active thrusts in this area: (1) engineering new NiTiHf alloys, both for additive manufacturing and for improved tribology materials and (2) discovery and design of improved soft magnetic alloys. These programs span basic research from the origins of hysteresis in materials to the applied optimization of compositions and processing of new materials for applications such as International Space Station ball bearings, additively manufactured biomedical implants, and high-efficiency, high-frequency transformers and power electronics for electric automobiles and airplanes.
