The structural relaxation process of amorphous Fe78B7Si15 and Fe82B13Si5 alloys has been studied by electrical resistivity measurements and Mössbauer spectroscopy. The topological distribution of first-neighbor iron atoms at an iron atom was changed and the average number of first-neighbor iron atoms increased during the change in topological short range order (TSRO) with irreversible changes of resistivity. Reversible changes of resistivity due to chemical short range order (CSRO) were observed in Fe78B7Si15 alloy which contained one kind of metallic atom. The resistivity decreased with increasing CSRO. The kinetics of CSRO in this alloy can be described as a log-normal distribution of relaxation times. The activation energy for the CSRO was estimated to be 222.0 kJ/mol from the resistivity measurement. This value is nearly equal to that for diffusion of Fe and Si atoms in Fe-based amorphous alloys. It is therefore likely that Fe and Si atoms play an important role in the CSRO of this alloy.
