Six amorphous alloys (Alloy 1: Fe₅₆Co₂₄Nb₄B₁₃Si₂Cu₁, Alloy 2: Fe_68.5Co₅Nb₃Cu₁Si_15.5B₇, Alloy 3: Fe_75.3Ni_0.8Cr_0.9Si_8.7B_14.3, Alloy 4: Fe₅₆Co₂₄Cr₁₀Nb₄B₃Si₁Cu₂, Alloy 5: Fe_72.9Nb₃Cu₁Si_16.2B_6.9, Alloy 6: Fe_83.3Si_8.6Nb_5.5B_1.4Cu_1.2) were selected in terms of their composition and magnetostriction constants and uniformly irradiated in a high radiation environment in Hall A of the Thomas Jefferson National Accelerator Facility. The 2 GeV electron beam irradiation-induced effects were characterized by Mӧssbauer spectroscopy. The microstructural changes were related to the evolution of the hyperfine magnetic field distributions and isomer shifts. In particular, the occurrence of stress centers in the amorphous materials was evidenced.
