Fig. 2. Evolution of the normalized storage modulus and loss modulus with temperature of Zr$_{50}$Cu$_{40}$Al$_{10}$ metallic glass (heating rate: 3 K/min, driving frequency: 1 Hz). $E_{u}$ is the unrelaxed modulus, assumed to be equal to the storage modulus at ambient temperature. Inset is the loss modulus and loss factor as a function of temperature
