| Abstract Scope |
Aluminum (Al) alloyed with cerium (Ce) and nickel (Ni) has proven extremely successful in producing stable intermetallics that maintain mechanical properties at elevated temperatures. However, many of these efforts require high amounts of alloying elements for adequate baseline mechanical properties, which can be costly. A practical and cost-effective way to enhance the mechanical properties of an alloy is by reinforcing it with ceramic particulates, such as alumina. Hypoeutectic Al-Ce-Ni alloys are an ideal candidate for metal matrix composites as they have relatively low surface tension compared to conventional alloys. Additionally, minor amounts of zirconium (Zr) enhance the work adhesion at the matrix-alumina interface. Therefore, this study characterizes the effect varying additions of Zr have on a hypoeutectic Al-Ce-Ni alloy reinforced with sub-micron alumina particulates. The comprehensive characterization of this alloy includes Thermocalc simulation, SEM, EDS, and XRD metallography coupled with indentation plastometry and tensile mechanical testing. |
