How a material is s haped into its final form is essential to a material’s structure (i.e.\, crystallographic structure\, phases\, microstructure\, macrostructure) an d\, therefore\, to its properties & performance. It is also critical in de termining the final product's functionality and is central to materials se lection and design. Within this context\, the overarching mission of the A dvanced Magnetic Materials Processing AM2P laboratory at Virginia Commonwe alth University is to engage in fundamental studies of microstructure to d evelop advanced functional magnetic materials with unprecedented functiona l performance.\n\nIn this talk\, I will discuss how the AM2P research grou p implements the use of advanced materials processing methodologies and a diverse set of cutting-edge experimental characterization techniques to ex amine relationships between processability\, materials structure\, and fun ctional response at different hierarchical length scales in rare-earth-fre e permanent magnets – a group of highly magnetized functional hard mater ials which do not lose magnetism over time due to the generation of the ma gnetic field by the internal structure of the material itself. The present ation will mainly focus on two types of permanent magnet alloys – (1) Al nico alloys - a phase-separated nanocomposite so-called due to their major ity composition of aluminum\, nickel\, iron\, and cobalt and (2) Tetrataen ite – a chemically ordered L10-type FeNi phase found only in meteorites in its native state. The end goal of these research efforts is to support innovative applications in the energy sector while improving the energy se curity of the United States by reducing imports of critical raw materials and energy from foreign sources.\n\nBiography: Radhika Barua is an Assista nt Professor in the Department of Mechanical and Nuclear Engineering in th e College of Engineering at Virginia Commonwealth University in Richmond\, VA.
