Abstract
The effect of Ca, Sc and Er microalloying on the microstructure and properties of AZ61 alloys by electromagnetic casting are investigated. Experimental results show that an addition of Ca, Sc and Er refine the grains and compounds of AZ61 alloy. Mg17-xCaxAl12 phase are obtained after Ca addition. When the Ca, Sc and Er added in AZ61 alloy, some new phase contain Ca, Sc and Er are appeared. The tensile properties are improved as a result of grains and compounds refinement arter Ca, Sc and Er microalloying.
