摘要：

The composition and the crystal structure of the phases in the alloys of Mg-Zn-Nd system at 400 degrees C have been studied by scanning electron microscopy (SEM), electron probe microanalysis (EPMA), Xray diffraction (XRD) and selected area electron diffraction (SAED) of transmission electron microscopy (TEM). The phase equilibrium relationships have been identified. As a result, a linear ternary compound T-2 phase has been identified. The general chemical formula of T-2 phase is (Mg, Zn)(11.5)Nd and the crystal structure of that is C-centered orthorhombic. As the results, the other three ternary compounds T, phase, T-3 phase and T-4 phase have also been identified. The partial isothermal section of phase diagram of Mg-Zn-Nd system at 400 degrees C has been established. (C) 2009 Elsevier B.V. All rights reserved.
