Phase analysis of Mg-La-Nd and Mg-La-Ce alloys

The ternary solubilities and solidification details of the Mg-Nd-La and Mg-La-Ce systems were examined through the evaluation of two alloys from each system. Thermodynamic parameters of the two systems were optimized using the observed phase constituents and measured ternary solubilities by SEM combined with the DSC signals of the four alloys. Isothermal sections at 500 °C and solidification paths of the two systems were evaluated.
