Results of measurements of positron lifetimes and X-ray diffraction in the annealed metallic glasses Fe_{78-x}Co_{x}Si_{9}B_{13} (x = 0, 20, 40, 60, 78) before and after the process of crystallization are presented. From the results it follows that the annealing process below the crystallization temperature causes changes in concentrations of positron-trapping areas and can be consistently described as the result of two contributions: topological and chemical short range ordering. The process of crystallization causes precipitation of α-Fe and β-Co crystalline phases and also formation of microvoids in the investigated samples.
