An ultra-high strength aluminum alloy was produced by casting and then extruded to rods.The effect of heat treatment on the microstructure and mechanical properties of the alloy was investigated.After single ageing(120℃,24 h),the tensile strength was 812.4 MPa and the elongation was 6.2%.After retrogression reaging(RRA),the tensile strength was 751.2 MPa and the elongation was 6.4%.The strengthening mechanism is considered as fine grain strengthening,substructure strengthening and dispersion strengthening by Al_3(Sc,Zr).
