title = "Effect of yttrium addition on microstructure and hardness of cast EV31A magnesium alloy",
abstract = "The effect of the rare earth element Y on the microstructure and hardness of (Mg-0.5Zn- 0.5Zr-2.8Nd -1.5Gd) wt% Mg alloy investigated. 1 wt. % Y was added and compared with the base alloy. The microstructure results show the refinement of the grain by the addition of Y and the grains became smaller about 31.8 % and the volume fraction was increases 11.1% %, which led to the increment of hardness from 48.33 HV (as-cast EV31A) to 53.71 HV (as-cast EV31A +1 Y). Energy dispersive spectroscopy and X-ray diffraction results showed that the base alloy mainly contained a-Mg matrix and Mg-(Nd, Gd) as a second phase crystallized along the grain boundaries and addition of(Y) yttrium resulted in the formation of the new phase, Mg-Zn-Y- phase was found as a new ternary phase, where Y combined with the original second phase.",
