Abstract
Six amorphous alloys (Alloy 1: Fe 56 Co 24 Nb 4 B 13 Si 2 Cu 1 , Alloy 2: Fe 68.5 Co 5 Nb 3 Cu 1 Si 15.5 B 7 , Alloy 3: Fe 75.3 Ni 0.8 Cr 0.9 Si 8.7 B 14.3 , Alloy 4: Fe 56 Co 24 Cr 10 Nb 4 B 3 Si 1 Cu 2 , Alloy 5: Fe 72.9 Nb 3 Cu 1 Si 16.2 B 6.9 , Alloy 6: Fe 83.3 Si 8.6 Nb 5.5 B 1.4 Cu 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 M ӧ ssbauer 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.
