Resumen:
Three age-hardenable Al-Cu-Mg alloys with different Cu/Mgratios were studied by means of positron annihilation lifetimespectroscopy and Vickers hardness as a function of the artificialageing time at 175 oC. Complementary information onthe decomposition sequence was obtained by means of differentialscanning calorimetry. The results are discussed in termsof the different structures that are formed during the precipitationsequence of the supersaturated solid solution.
