Conclusions
-
1.
It was found that two primary intermetallic phases, MnAl6 and ZrAl3, can be formed in Al−Mg — Li alloys with additions of manganese and zirconium. To reduce the amount of intermetallic phases it is necessary to reduce the iron content of the alloy.
-
2.
The tendency of alloys with manganese to form intermetallic compounds based on ZrAl3 is lower than for alloys without manganese at iron concentrations of 0.2% or higher.
