Abstract

The research results on the development of a new generation Mg-REM-Zr fire-safe magnesium casting alloy system are presented. Serial magnesium alloys do not have both high strength at room temperature and a sufficient level of heat resistance. A unique domestic foundry magnesium alloy has been developed with consistently high specified properties at the same time. In addition, the obtained ignition temperature indicators of the developed alloy allow it to be attributed to the group of fireproof magnesium alloys. The conducted studies of the its heat treatment parameters made it possible to choose the optimal mode that ensures the achievement of high strength characteristics of the alloy.
