dc.description.abstract | Very inherent metastable character of amorphous metal alloys, induces structure phase transformations which manifest themselves in thermally activated relaxation processes. The kinetics of these processes can be interpreted with the aid of two models: two equilibrium states and spectrum of activation energies. Structure relaxation of amorphous Fe40Ni40B20 metallic glass has been observed by measuring changes in electrical resistivity at corresponding isothermal treatments. Electrical resistance changes have been measured at liquid nitrogen temperature (78 K) using the d.c. method and a fixed probe. By measuring the resistivity change during isothermal treatment, logarithmic kinetics has been observed. Also, Q(E) function has been derived having a symmetric distribution around the value of activation energy of 2.1 eV, determined by some other methods too. | en |
