| Abstract Scope |
Aluminum-cerium (Al-Ce) and Al-Ce-manganese (Al-Ce-Mn) alloys have been researched with respect to the automotive and aerospace industry providing successful results for a new generation of alloys. These alloys show promise for elevated temperature applications with improved mechanical retention above 200°C. Additions of nickel (Ni) to different Al alloys also shows promising results for elevated temperature strength, but little research has been done on the Al-Ce-Ni-Mn system. To further characterize this alloy system, this paper focuses on an Al11.3Ce3.2Ni1.2Mn alloy. The alloy was cast in a steel wedge mold to replicate different cooling rates. Optical and SEM/EDS microscopy were used for SDAS measurements and identifying the phases present at different cooling rates throughout the casting. Correlating the metallography resulting to solidification rates and elevated-temperature mechanical property retention will further characterize the Al-Ce-Ni-Mn system. In turn, this will help the automotive industry in developing Al-based alloys for high performance powertrain applications. |
