Abstract

Microstructures and mechanical properties of Mg-2.0%Ce-0.7%Zn-0.7%Zr alloy were studied. The results of scanning electron microscopy show that Mg12Ce phase mainly distributes at the grain boundaries. The fine Mg12Ce phase can apparently elevate recrystallization temperature by preventing the grain boundary migration. No dynamic recrystallization occurs during the hot-extrusion. The mechanical properties of as extruded specimens are σb=278.5 MPa, δ=12.0%, while those of the specimens annealed at 250 °C for 100 h are σb=272.6 MPa, δ=11.3%, which indicate that the alloy has good mechanical properties at room temperature.
