摘要：
Transmission electron microscopy (TEM) and atom probe tomography (APT) were employed to investigate the solute clusters and precipitates formed in different Mg-Nd-Zn-Zr-Gd/Y alloys aged at 200 degrees C up to 100 h. TEM characterizations confirmed the precipitation in these alloys involved the formation of precipitates such as beta '', beta', beta 1 and beta Most precipitates habited on (01 (1) over bar0)(alpha-Mg) and a few thin plate (of 1-2 atomic layers in thickness) lying on (0001)(alpha-Mg). APT analyses revealed that the precipitates were enriched with Nd, Zn and Gd. Moreover, Nd partitioned more strongly into the precipitates than Gd and Zn. In contrast, Y was less prone to partition into precipitates than other alloying elements in these alloys.
