Abstract

[ $Mg_{97}Zn_1Y_2$ ] alloy powders were prepared from gas atomization process, followed by consolidation using spark plasma sintering (SPS) process. The atomized $Mg_{97}Zn_1Y_2$ alloy particles were entirely spherical in shape and dendritic microstructure. The compacts sintered by SPS process had theoretical density more than 99%. The compressive yield strength was decreased as sintering temperature increased. It was found that the compressive strength showed the maximum value of 303MPa at the $Mg_{97}Y_2Zn_1$ specimen sintered under load of 255 MPa at $350^{\circ}C$.
