Abstract: Microstructures and tensile properties of Mg-6Zn-lY-l Ce alloy extruded in a
temperature range between 300 °C and 400 °C were investigated. The yield strength of the
material increased as the extrusion temperature decreased due to grain refinement. The yield
strengths and grain sizes of extruded samples met Hall-Petch equation. The microstructure of the
alloy extruded at 300 °C had a bimodal grain size distribution with an average grain size of 2.7
7mu;m and showed a yield strength of 327 MPa with an elongation of 9%. The fine-grained
microstructures were attributed to the dynamic recrystallization and the pinning effect of fine
strengthening particles. © Wuhan University of Technology and SpringerVerlag Berlin Heidelberg
