Abstract

The glass forming ability and thermal stability of melt-quenched Cu 60Zr22Ti18 amorphous alloy were studied by differential scanning calorimetry. The evolution of the microstructure during continuous and isothermal heat-treatments was characterized by X-ray diffraction. In order to investigate the crystallization kinetics, the alloy was annealed near the glass transition temperature for different annealing times ranging from 5 to 120 min. After these pre-anneals, a subsequent continuous heating was carried out. Based on the classical nucleation theory, the transformed volume fraction was evaluated from these measurements.
