Abstract
This paper investigates the crystallization kinetics of Zr 60 Al 15 Ni 25 bulk glassy alloy under isothermal annealing by differential scanning calorimetry (DSC). The results show that the incubation time is very small even at low annealing temperature (743 K) and increases slightly with the annealing temperature decreasing, which suggests a growth-controlled crystallization process. However, the exothermic peak width, reflecting the time for the actual crystallization process, increases greatly when annealing temperature decreases. The Avrami exponents indicate that the crystallization mechanism changes at different annealing temperatures. The change of the crystallization mechanism is attributed to the great difference of the mobility ability of atoms at different temperatures.
