摘要：

Early stages of transformation of a metastable Al4.4Cu1.7Mg alloy have been studied by DSC, microhardness and TEM, during natural ageing. The progressive disappearance of the first exothermal signal of the as-quenched material, the corresponding initial hardness increase, and TEM/SAD observations, suggest the formation of GP + GPB zones.
