Crystallization behavior of Zr60Cu20Fe10Al10 amorphous alloy
Source abstract
Abstract
Abstract The crystallization behavior of Zr60Cu20Fe10Al10 amorphous alloy was studied using non-isothermal differential scanning calorimetry. The overall crystallization activation energies determined using the Kissinger and Ozawa methods were 240.9 ± 6.4 and 241.2 ± 6.0 kJ/mol, respectively. The local activation energies, which were calculated using the Ozawa–Flynn–Wall method, indicated a three-stage crystallization process. The local Avrami exponents were calculated to characterize the competition between crystallite nucleation and growth. In situ heating transmission electron microscopy observations confirmed the theoretical predictions.
