and Mg24RE5. The results are consistent with the EDS analysis of the as-extruded alloy specimen. However, the metastable phase formed during aging process is hardly detected because of the small volume...-aged alloy, the improvement of mechanical properties is mainly attributed to the fine β′ precipitates[5, 10]. The β′-phase precipitating on the prismatic planes, which exhibits semi-coherent structure......

properties. SEM observations and EDS data show that β-phase of Al12Mg17 precipitates continuously or discontinuously from α-Mg matrix and distributes along grain boundaries of the AZ80 alloy during... or natural aging play an important role in hardness and strength level of the Mg alloys with high Al or rare earth content. For the solution-treated Mg alloys with relatively high Al content, β-phase......
