Phase transformation and crystallization kinetics of Te67.5Ga2.5As30 amorphous alloy
چکیده انگلیسی

The amorphous to crystalline transformation in Te67.5Ga2.5As30 occurs under non-isothermal conditions. The crystallization parameters of this amorphous material are estimated using differential scanning calorimetery (DSC). The activation energy of crystallization (Ec) and the frequency factor (K0) are calculated to be 113.16±1.5 kJ/mol and 1.04×1010±31.70 s−1, respectively. The crystallization mechanism is found to be one-dimensional growth mechanism as indicated from the estimated Avrami exponent value. X-ray investigations confirm the amorphous phase and crystalline state for the as-prepared and annealed samples, respectively. The crystallized grain sizes of nanoscale are calculated from the XRD peaks.
