Abstract
The precipitation sequence of a Mg-2.1Gd-0.6Y-0.2Zr (at.%) alloy at 200 °C was investigated by transmission electron microscopy (TEM), and the chemical compositions of the precipitates observed in different stages of the sequence were analyzed by the three-dimensional atom probe (3DAP) technique. The precipitation sequence is described as supersaturated solid solution (SSS) â βⳠ(D019 Mg3X) â βⲠ(bco Mg15X3) â β phase (Mg5X). There are structural similarities in each phase and the phase evolution occurs continuously by decreasing the rare earth content when βⳠtransforms to βâ².
