Intergranular microstructure of cast Mg-Zn and Mg-Zn-rare earth alloys

• The solidification path and microstructure of cast Mg-9Zn and Mg-8Zn-1.5 MM (misch metal) alloys have been investigated by a combination of thermal analysis and analytical electron microscopy. The addition of 1.5 wt pct MM had a strong influence on the as-cast microstructure with the introduction of new `ternary' interdendritic phases and structural modification of known binary phases. The temperature ranges for formation of these phases from the melt were identified, their crystal structures determined, and their compositions analyzed. Products from eutectoidal decomposition of the interdendritic phase in the binary Mg-9Zn alloy were also identified
