The isothermal section of the La-Ag-Mg phase diagram at 400°C

Description

The whole isothermal section of the La-Ag-Mg phase diagram at 400 °C was constructed by means of phase identification and analysis on about eighty annealed ternary alloys. The tendency of Ag and Mg to reciprocally substitute in binary Ag-Mg phases reflects in the formation of several La-Ag-Mg ternary phases including solid solutions based on boundary binary phases, which show wide homogeneity regions extending at a constant La-content. Among the solid solutions, La(AgxMg1-x) (0
