| Abstract: | Structure relaxation occurred in Fe 78 Si 9B 13 amorphous treated by ultrashort electropulsing. The crystallization activation energy has been calculated by DTA and Kissinger equation.The variety of the zero recoil fraction has been investigated by Mssbauer spectroscopy. The result shows that the crystallization activation energy and the zero recoil fraction decreased when the electropulsing density and frequency increased. It indicated that the atom binding force of Fe 78 Si 9B 13 amorphous decreased accordingly. |
