Abstract

Invariant three- and four-phase equilibria in the magnesium-rich corner of the Mg-Cu-Sn ternary system have been studied by differential thermal analysis, optical microscopy, electron probe microanalysis and X-ray diffraction. The L⇋(Mg) + Mg2 Cu + Mg2Sn ternary eutectic reaction was found to be at 467 °C and at Mg−13.5 at % Cu−4.4 at% Sn. The L⇋Mg2Cu + Mg2Sn pseudo-binary eutectic reaction is tentatively located at 522°C and at Mg−26.0 at % Cu−7.7 at % Sn.
