Paper Title:
Precipitation Behavior of Mg-Y-Nd-Zr Alloy
  Abstract

The precipitation behavior of Mg-Y-Nd-Zr alloy was investigated by using transmission electron microscopy. The precipitation sequence of Mg-Y-Nd-Zr alloy was confirmed as follows ; Supersaturated solid solution → β''→ β'→ β.The β'' phase was identified Mg3Nd having DO19 structure with the lattice constant of a=2aMg=0.64nm and c=cMg=0.52nm. The β' precipitate was identified as Mg12NdY having base centered orthorhombic structure with the lattice constants a, b and c of 0.64, 2.23 and 0.52 nm, respectively. The β phase was confirmed as equilibrium phase having the fcc structure with the lattice constant of a=2.22 nm.
