Summary

Very recently, an investigation conducted on the creep behavior of a 15 vol. % silicon carbide particulate reinforced PM magnesium AZ 91 and QE 22 alloys has shown [3] that the reinforcing effect of SiC particles on the creep resistance is not uniform and depends strongly on the matrix alloy. While the creep resistance of AZ 91 alloy was increased by the particle reinforcement, the creep resistance of the reinforced QE 22 was decreasing with a decrease in the particle size. In order to find out the reason for such unexpected trend in the creep behavior the microstructure and its changes induced by creep loading in a QE 22–SiC composite have been investigated by means of analytical electron microscopy in this work.
