Abstract Scope Al-Fe-Ni eutectic alloys have high potential to replace conventional low-conductivity Al casting alloys for various electronic and electrical applications. Furthermore, the addition of Zr and Sc up to 0.3 wt% improves hardness and thermal stability for higher temperature applications, which is a result of the fine Al-Fe-Ni eutectic structure and precipitation hardening by Al3Zr and/or Al3Sc nanoprecipitates. Thus, the aim of this study was to analyze the microstructure changes in an Al-1.75 wt% Fe-1.25 wt% Ni eutectic alloy with Zr and Sc additions upon different cooling rates during solidification. The morphology and dimensions of Al-Fe-Ni eutectics, constitutive intermetallics and eutectic grains were examined in relation to the cooling rate. Mechanical properties and electrical conductivity were examined and correlated to the structure changes.
