Abstract
In this study, the crystal structure, surface morphology, and formation of free clusters in amorphous ribbons with Fe93Si6C1 composition were investigated. Fe93Si6C1 amorphous ribbon samples were produced using the melt spinning technology, which is widely used in the preparation of amorphous materials. This process prevents crystallization in the microstructure of the ribbon, thereby improving its magnetic, mechanical, and electrical properties. This paper examines the effect of irradiation with 2.5 MeV H+ ions at doses of 2.5 x 10(13), 2.5 x 10(14), 2.5 x 10(15) ion/cm(2) on the microstructure of Fe93Si6C1 amorphous ribbons. The results of the SRIM simulation showed that ions penetrate to a depth of similar to 27.6 mu m in the amorphous ribbon, causing the formation of radiationinduced defects up to this depth. Post-irradiation analysis with X-ray diffraction revealed significant structural changes. The Rietveld refinement method showed that the alloy consists of three phases: Fe (Fm-3m cubic), FeSi (P213 cubic), and Fe2C (Pnnm orthorhombic). Although the initial amorphization analysis revealed that the sample had approximately 81.7 % amorphous content, this value was found to decrease to similar to 80.6 % after the maximum irradiation dose. The irradiation also resulted in an increase in free volumes, as well as spherical and cylindrical radius within the amorphous ribbon.
