The hardening phase evolution in a QE22 Mg alloy is followed by differential scanning calorimetry, microhardness and transmission electron microscopy, after different thermal treatments. The decomposition of the supersaturated solid solution occurs via the formation of nanometric coherent structures (co-clusters or GP zones) followed by the co-precipitation of two metastable phases responsible for the peak ageing condition. The stable phase (Mg,Ag)12Nd appears at the highest annealing times, giving rise to overageing and hardness reduction. TEM observations provide information on the crystallographic structure of the forming phases
