Mg-Ce alloys. Experimental investigation by Smith thermal analysis

The magnesium-cerium system has been partially revised in the Ce-rich and M g-rich regions by using results obtained with the Smith thermal analysis (S TA) technique. Nine alloys were examined and, after the thermal measurement s, were subjected to phase analysis by means of X-ray powder diffraction (X RD), optical (LOM) and scanning electron microscopy (SEM), and electron pro be microanalysis (EPMA). The coordinates of the invariant reactions, many o f them very close to each other, were established and compared with literat ure data where a call for a deeper investigation was proposed as the therma l values were open to different interpretations.
