Orlando Rios at University of Tennessee Knoxville (UTK) leads the CMI project "Science-Enabling Diverse Value Chain Product from Aluminum-Cerium Alloys"

This work targets specific science problems to enable diverse value chain development for aluminum-cerium alloys, identifying interfacial structure and reaction thermodynamics for better strength at elevated temperature, higher ductility, and lower cost. The project investigates the use of rare earth element precursor compounds as feedstock for direct reduction alloying. This technology can be used for large volume casting technologies like die casting and high-performance applications such as turbochargers, pistons, and cylinder heads. If successfully developed, this technology will streamline processing of lanthanide precursor compounds improving economic competitiveness and providing a domestic demand stream through aluminum alloying.
