The Influence of Strontium on the Microstructure of Cast Magnesium Alloys Containing Aluminum and Calcium
Keyword(s):
The influence of strontium addition on the microstructure of a Mg-9Al-2Ca alloy was investigated. The microstructure of Mg-9Al-2Ca-xSr alloys consists of α-Mg, (Mg,Al)2Ca with C15 structure, Al4Sr and AlxMny phases. The addition of strontium decreases the grain size of the α-Mg phase and decreases the aluminum content dissolved in the α-Mg solid solution. Moreover, the volume fraction of the Al4Sr phase increases with increasing strontium content. Strontium does not influence on the volume fraction of (Mg,Al)2Ca phase.
