Abstract

The given article presents the results of the research of micro- and macrostructure of magnesium-zirconium additional alloy, preliminary alloy MTsr1N3 and alloy ML10 made of the listed batched materials. The alloying is hard for the elements melting points of which are higher than the melting point of magnesium. The zirconia alloying of magnesium alloys is processed through the preliminary magnesium-zirconium additional alloy melting points of which are lower than the melting point for zirconium. The zirconia alloying of light alloys is difficult not only because the melting points for zirconium are too high, but because of its activity as well: zirconium interacts with hydrogen, oxygen, nitrogen, aluminum, ferrum, silicon, carbon and other elements. The origins of contamination of magnesium alloy ML10 with the elements that are infusible with magnesium, such as intermetallides of zirconium and aluminum or ferrum or silicon and molecular entities of zirconium-oxygen and zirconium-hydr
