Al–Cu–Ni alloys are of scientifi c and technological interest due to high strength/high temperature applications, based on thereinforcement originated from the interaction between the Al-rich phase and intermetallic composites. The nature, morphology,size, volume fraction and dispersion of IMCs particles throughout the Al-rich matrix are important factors determiningthe resulting mechanical and chemical properties. The present work aims to evaluate the effect of the addition of 1wt%Ni intoAl–5wt%Cu and Al–15wt%Cu alloys on the solidification rate, macrosegregation, microstructure features and the interrelationsof such characteristics on tensile and corrosion properties. A directional solidification technique is used permitting awide range of microstructural scales to be examined. Experimental growth laws relating the primary and secondary dendriticspacings to growth rate and solidification cooling rate are proposed, and Hall–Petch type equations are derived relating theultimate tensile strength and elongation to the primary dendritic spacing. Considering a compromise between ultimate tensilestrength and corrosion resistance of the examined alloys samples from both alloys castings it is shown that the sampleshaving more refined microstructures are associated with the highest values of such properties.
