摘要：

The effects of Pd on the microstructure and mechanical properties of Mg-6Al-1Zn alloys were investigated Mg-6Al-1Zn-xPd (x = 0-6 wt %) alloys were prepared using a permanent mould casting method The microstructure of the as-cast alloys was characterized by the presence of Mg17Al12 and Al4Pd phases The volume fraction of the Al4Pd phase was increased by the addition of 1-6 wt % Pd but the volume fraction of the Mg17Al12 phases decreased At room temperature the tensile strength increased with increasing Pd addition up to 2 wt % Pd and the elongation to fracture decreased with a concomitant increase in the aggregation of the coarse Al4Pd phase At 150 C the tensile strength increased with the addition of Pd Therefore the room and elevated temperature tensile properties of as-cast Mg-6Al-1Zn alloys can be improved by Pd addition (C) 2010 Elsevier B V All rights reserved
