Abstract

The samarium-magnesium system has been investigated by means of differential thermal analysis, X-ray diffraction, metallography and microprobe analysis. Five intermetallic compounds have been found to exist: SmMg (m.p. 800°C), SmMg2 (m.p. 750°C), SmMg3 (decomposes at 700°C), SmMg5 (decomposes at 565 °C) and Sm5Mg41 (peritectic decomposition). Eutectic points occur at 45.0 at.% Mg (785°C), 64.5 at.% Mg (735°C) and 92.0 at.% Mg (530°C). A eutectoidal reaction is observed at 580 °C and 20.0 at.% Mg. The crystal structures of the intermediate phases have been confirmed or determined and the lattice parameters measured. © 1989.
