| Abstract | Microstructure evolution of a supersaturated solid solution Mg-2.2 wt%Nd alloy during aging at 240 degrees C for 6 h (stage I), at 295 degrees C for 3 h (stage II), and finally at 320 degrees C for 1 h (stage III) was studied by in situ synchrotron X-Ray diffraction. In stage I, diffraction from beta(1) (Mg3Nd, FCC) precipitates was observed after similar to 15 min. Evolution of the volume, size, and aspect ratio of beta(1) with the aging time were estimated from peak intensity and peak width analysis. In stage II, diffraction from beta (Mg12Nd, tetragonal) precipitates was observed after similar to 36 min while beta(1) remained in the material. In stage III, the volume of h reduced substantially in relative to beta. The identified precipitation sequence from the in situ aging experiment is supported by ex situ electron microscopy observations. beta', which had not been detected by synchrotron X-rays, was additionally found using transmission electron microscopy in the material by the end of aging stage I. Tension and hardness tests using specimens with different aging conditions were further performed to understand how different precipitates affect the strength and ductility of the Mg-Nd alloy. |
