Abstract

The new type 5083 aluminum alloy can be strengthened by heat treatment with the addition of 0.6 wt% Ag. Ag increased the stability of G.P. zones which provided nucleation sites for β′′ phase. β′′ phase had an ordered cubic L12 type crystal structure with a lattice parameter of a = 0.408 nm and was primary strengthening phase in the new type 5083 aluminum alloy when aged at 160 °C. The tensile strength of the peak-aged stages of the alloy was 448.9 MPa and the yield strength was 272.8 MPa which increased 39.9 and 88.3 MPa than the as-quenched alloy respectively. The precipitate phase at the over-aged stages was T phase which was body centered cubic structure with a composition of Mg32(Ag,Al)49.
