Effect of anti-site point defects on the mechanical and thermodynamic properties of MgZn2, MgCu2 Laves phases: A first-principle study

The coexistence of ionic and covalent bonds in defect phase Mg5Zn7 (Cu15Mg9), which is obtained from Mg anti-site defect on Zn (Cu) site, resulting in the characteristics of high modulus.466
