Abstract Scope |
Cerium inclusion in aluminum alloys reveals a complex microstructure that has improved mechanical and electrochemical properties. Tribological mechanical characterization performed via CAT (Characterization via Automated Tribology) testing, corrosion testing, high-temperature hardness testing, and tensile testing, has been used to develop a materials properties database for aluminum-cerium alloys. Tensile and hardness testing were performed on samples at increasing increments of temperature to relate mechanical properties and thermal energy. Electrochemical properties were determined by analyzing data collected on the alloys via scratch testing. Innovative procedures for rapid characterization have improved the quality and accessibility of information guiding manufacturing decisions, such as adjusting sample compositions and process parameters. These techniques are used to optimize refinement of aluminum-cerium alloys for applications in renewable energy and the automotive industry, and generate significant interest in Al-Ce alloy production which reduces cerium waste while increasing economical value in byproducts of rare earth mining. |
