Abstract
The elastic constants of several Al-based icosahedral alloys were meas ured over a temperature range from 4 K to 1073 s by the rectangular pa rallelepiped resonance method. The values of the bulk moduli of these quasicrystals are similar to those of conventional cubic crystals havi ng similar melting temperatures, while the values of Young's and shear moduli are larger in comparison with conventional aluminium alloys. T he latter feature is considered to be due to the strong directional bo nding in the quasicrystals.
