The Structure and Phase Composition Stability of Amorphous Zirconium irradiated with Helium Ions

Abstract

Amorphous alloy samples based on Zr with additional metals were irradiated using He ions at operating energy of 40 KeV under room temperature conditions with fluence from 5·10 17 to 7·10 17 cm-2. The phase analysis of the samples is conducted using an X-ray diffractometer (Rigaku). XRD analysis revealed formation of amorphous, crystalline and amorphous+crystalline structure of Zr base foils. It was found that irradiation with helium ions does not lead to a change in the structure of the foils. It was found that irradiation with helium ions leads to a shift in the diffraction peaks of crystalline phases to the region of smaller angles for all crystalline and crystalline amorphous foils. And irradiation with helium ions leads to a decrease in the angular position of the amorphous halo
