Three Al-Cu-Mg-Fe-Ni-Sc-Zr ingot metallurgy alloys with different compositions had been prepared. The hardness variations of cold-rolled alloy plates during annealing process had been measured. The tensile properties at both ambient and elevated temperatures were also measured. The microstructures of alloys were observed by using optical microscope and TEM. It was found that the dispersed Al3(Sc, Zr) particles could pin dislocations, stabilize substructures and impede the movement of boundaries. The ambient and elevated temperature properties of alloy with Al3(Sc, Zr) particles were improved. And the tensile strength of alloy did not improve obviously with rich iron and nicker addition.
