The atomic structure of amorphous phases in ZrNi system prepared by fast quenching (FQ) and mechanical alloying (MA) are compared on an atomic scale using the reduced radial distribution function G(r), then investigated by thermal methods. The amorphous structure is characterized by X-ray diffraction (XRD). Differential scanning calorimetry (DSC), was used to investigate the crystallization kinetics. It is found that both FQ and MA ZrNi specimens have similar crystallization kinetics under non-isothermal conditions. However, the FQ ZrNi is much more stable compared with its MA counterpart. |
