摘要: Abstract The effect of yttrium addition on fundamental characters magnesium has been investigated by calculated and experimental methods. It was found that the lattice parameter increased axial ratio c / a decreased with increment in solid solution. approximately linear relationship between Young's modulus content solution observed single phase Mg–Y alloys (T4 state). However, closely relevant to fraction second precipitate except saturated matrix for aged (T6 concentration vacancy solution, which mainly caused atomic size misfit difference valence electrons magnesium.
