The Cu-Li-Mg system still remains very unknown. Mel'nik et al. (Russ. Metal
l. 3 (1976) 152-156) studied it at 643 K. They considered the existence of
a stoichiometric compound Cu8Li2Mg15 with an orthorhombic structure.
In this work, the Cu-Li-Mg system was studied at room temperature by means
of SEM (scanning electron microscopy) / EDS (energy dispersive spectroscopy
) and X-ray diffraction. Results were compared with the ones from (Russ. Me
tall. 3 (1976) 152-156) and with the assessments for the binaries Cu-Li, Cu
-Mg and Li-Mg present in the literature (COST-507, Thermochemical database

Sciences, European Commission DGXII Publ., 1994, pp. 132-134; A.A. Nayeb-Ha
