The compositional dependence of thermal and elastic properties of Cu-Zr-Be ternary bulk metallic glass forming alloys was systematically studied. There exists a linear relationship between the glass transition temperature Tg and the total Zr concentration. G decreases linearly with increasing Zr concentration as well. The results also show that Tg, shear modulus G, and Poisson's ratio V are very sensitive to changes in compositions. Low Tg, low G, and relatively high v can be achieved with high Zr and Ti concentration.
