As light-weighting has become a primary concern in modern industrial and material design, aluminum alloys have seen broader application. However, their poor performance at elevated temperature has required manufactures to choose high-cost or heavier options at temperatures over 150C. Alloys of aluminum with cerium as the primary addition exhibit superior high-temperature mechanical properties, low-density, and low cost making them a prime candidate to fill the techno-economic gap in the market at high-temperature. This presentation will focus on the continued progress in the development of the novel Al-Ce alloy family. Topics of discussion will include the effect of alloying additions, die-casting, corrosion properties, cooling rate sensitivity, and high-temperature mechanical properties.
