Abstract: The ageing behavior and microstructures of the Al-Mg-Li alloys containing small amounts of silver have been studied. The results showed that small quantities of silver could modify the ageing characteristics of Al-Mg-Li alloys, enhance the peak hardness and strength, and delay the ageing peaks. X-Ray diffraction analysis showed thatTphase was present in the Al-Mg-Li alloy containing 0.52%(mass fraction, %) Ag, and TEM observations showed that silver prevented the growth of δ′phase during ageing.
