Abstract: (Cu0.56Zr0.44)(100-x)Al-x series bulk metallic glasses were prepared by using copper mould suction casting method. The thermal parameters were obtained by thermodynamic analysis. Longitudinal and shear ultrasonic velocities were measured by water-immersion focusing method and the elastic parameters were calculated. Results show that the elastic properties are improved with increasing Al content, which is attributed to the stronger interaction of Al-Zr than Cu-Zr. Furthermore, the more the elastic properties, the higher some of the thermodynamic parameters such as Delta T, T-x, T-g/T-1 and T-x/T-m are. (C) 2009 Elsevier B.V. All rights reserved.
