Abstract Scope |
The manufacturing associated with emerging technologies, including electric vehicles, is impacting demand for cast aluminium alloys, including those based on the Al-Ni system. These alloys typically have a eutectic with a fine lamellar spacing in the as-cast condition, display high thermal stability, high electric conductivity, resistance to hot tearing, good fluidity, and strength. These properties combined make this alloy system suitable for a variety of applications. This research investigates the effect of varying the concentration of Ni on the solidification mode, microstructure, and fluidity of Al-Ni alloys. Hypoeutectic, eutectic, and hypereutectic compositions of Al-Ni from 0 to 10wt.% were investigated, and it was found that hypereutectic Al-7.7wt.%Ni alloy had the best fluidity. As cast microstructures as well as quenched microstructures during solidification and sample cooling curves were compared to investigate microstructure evolution in the Al-Ni system. |
