| Abstract Scope |
Aluminum alloys have found applications in the automotive and aerospace industries; however, the loss of their properties at high temperatures has limited their applications. In recent years, Al-Ce alloys have been developed since they can maintain their mechanical properties up to 350 °C. The proposed research aims to reduce the cost of producing Al-Ce alloys by incorporating low-cost CeO2 into Al-Ni-Cu-Mg melts to form Al-Ce alloys through an aluminothermic reduction process. The microstructure and selected mechanical properties of the cast alloy were characterized. The formation of Al-Ce intermetallic compounds as a result of the reduction of CeO2 to Ce compounds was demonstrated using optical microscopy, XRD, and SEM. The formation of other intermetallic Ce compounds, including Al3Ni and Al23Ni6Ce4, was observed when Ni was present in Al melts. The presence of Ni, Cu, and Mg appears to facilitate the reduction process, leading to the formation of these intermetallic compounds. |
