The structures, elastic anisotropy, toughness, and Debye temperature of the Al-Ni crystal are analyzed by using the density functional theory: PW91. The results show that AlNi is the most anisotropic of all phase, and the Al3Ni2 is the most isotropic of all phase. In addition to Al3Ni and Al3Ni2 are brittle materials, other intermetallics are tougher materials. Among which, AlNi has the best toughness, and Al3Ni2 has the best brittleness. The study of Debye temperature suggests that Al3Ni has the highest Debye temperature, AlNi has the lowest Debye temperature.
