Abstract. The liquidus curve for the Mg-Pb system was redetermined, and its slope was used to assess phase transformations in the β' + Pb-rich liquid phase field. A peritectic reaction occurred at 538.7 °C when Mg 2 Pb decomposed into a Mg-rich liquid and β' (a Mg-Pb compound containing 35.15 at. pct Pb, or 0.3515 N Pb, the atomic fraction of Pb) which melted congruently at 548.5 °C, confirming the work of Eldridge et al.
