Study on the intermetallic phases in the Mg-Ce system Part II. Diffusion couple investigation

Mg-Ce diffusion couple annealed at 400 degrees C was investigated via electron probe microanalysis (EPMA), and scanning electron microscopy/energy dispersive spectroscopy (SEM/EDS) The results validated the compositions of the intermetallic phases experimentally determined by Zhang et al. [1] on the Mg-rich side of the binary phase diagram and refined the phase diagram suggested by Zhang et al. [2] for the composition range of 38-70 wt% Ce A revised equilibrium phase diagram was proposed for the Mg-Ce system up to 50 at% Ce. (C) 2010 Elsevier B V All rights reserved.
