摘要: The microstructure of the Mg—6% Gd-3.7% Nd-0.3% Zn-0.18% Y-0.15% Zr (% wt) alloy has been investigated after solution treatment at 540° C for 24hr followed by isothermal aging at 175° C up to 32 days by using of Vickers hardness, optical microscopy, scanning electron microscopy equipped with EDS, X-ray diffraction and transmission electron microscopy. It was observed that the homogenized alloy contained primary α-Mg solid solution, eutectic structures, cuboid shaped phases and Zr-rich clusters. The eutectic structures were the …
