Abstract
Low frequency internal friction and differential scanning calorimetry were applied to investigate calorimetric glass transition as well as relaxation characteristics of the supercooled liquid states in a bulk metallic glass-forming Zr46.75Ti8.25Cu7.5Ni10.0Be27.5 alloy. A dramatic decrease in structural relaxation time of the supercooled liquid was exhibited by internal friction measurements. The dependence of temperature on the relaxation time fits well with the Vogel–Tammann–Fulcher form. Based on the free volume theory the calorimetric glass transition was explained as the relaxation of supercooled liquid inspired at the experimental timescale. The results exhibit that the calorimetrical glass transition is a mainly kinetic process in this glass.
