Abstract: Information of solidification processes, liquidus temperatures, and phase relationship of the Mg-Mn-Y system in the Mg-rich corner was systematically studied using differential scanning calorimetry (DSC) measurement, x-ray diffraction (XRD) analysis and scanning electron microscope (SEM) analysis. One single-phase region (Hcp), two two-phase-equilibrium regions (Hcp + Cbcc & Hcp + Mg24Y5), and one three-phase-equilibrium region (Hcp + Cbcc + Mg24Y5) were identified in the Mg-rich corner at 550 °C in this work. No ternary phase was observed within the currently studying composition range. Corresponding calculations using the current available thermodynamic description of the Mg-Mn-Y system for the comparison with experimental results were performed. The experimental and calculation results show certain deviations in the phase transition temperatures and the tie-lines of the equilibrium phase regions. The differences are attributed to the extreme low concertation of alloying elements alloyed in Mg in this work, where few studies were performed in literature and nevertheless included in the previous assessment work. Therefore, the current results could provide an essential basis for the further study and revision of the thermodynamic description of the Mg-Mn-Y system and the design/development of new alloy and process of Mg-Mn-Y based alloys.
