The new type 5083 aluminium 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 aluminium alloy when aged at 160℃. 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 MPa and 88.3 MPa than the as-quenched alloy respectively. The precipitat phase at the over-aged stages was T phase which was body centered cubic structure with a composition of Mg32(Ag, Al)49.
