| Abstract | Elastic and thermodynamic properties of the XAl3 (X= Sc,Ti, Fe, Ni,Y, Zr and Ta) intermetallic compounds were investigated by means of first-principles calculations within the framework of density functional theory. The single-crystal elastic constants were calculated, showing that the XAl3 intermetallic compounds are mechanically stable structure. Then the bulk modulus B, Young's modulus E, shear modulus G and Poison's ratio vwere estimated for polycrystalline Al3X from the elastic constants by the Voigt-Reuss-Hill(VRH) approximation. The ductility of XAl3 intermetallic compounds was analyzed, and FeAl3 and ZrAl3 compounds are ductile. The elastic anisotropy was also further discussed in details. Finally, thermodynamic properties such as the Debye temperatures, the specific heat for the XAl3 intermetallic compounds were estimated from elastic properties. |
