英文摘要：
The elastic properties of $Cu-Al-Mn$ alloys with compositions along the $Cu_3Al \to Cu_2AlMn$ line and $bcc$-based structures, are studied by means of first-principles calculations. From the calculated elastic constants, the Zener's anisotropy, sound velocities and Debye temperature are determined. The theoretical results compare well with the available experimental data. The influence of vibrations is introduced through the quasi-harmonic Debye model, and different properties are studied as functions of temperature and composition.
