This work analyzes and summarizes the results of an investigation of ternary phase diagrams of magnesium with two rare-earth metals of different subgroups, conducted in IMET RAS in connection with the development of high-temperature magnesium alloys. During this investigation a number of regularities in the constitution of the studied phase diagrams were discovered. They allow explaining the effect of the applied alloying elements on the properties of magnesium alloys. They also make it possible to predict the phase diagram type of magnesium with other rare-earth metals and their properties.
