Dimensional Changes of Amorphous Alloys Under Swift Ar Ion Irradiation

  •  Institute of Modern Physics, The Chinese Academy of Sciences, Lanzhou, China

  • Small strips of amorphous alloys Fe77.2Mn0.8Si9B13, Fe39Ni39V2Si12B8, Fe47Ni29V2Si6B16, and Fe40Ni40Si12B8 were irradiated below 50°K with 2.79 MeV/u Ar ions delivered from Heavy Ion Research Facility in Lanzhou (BDDRFL). The macroscopic dimensions of the samples were measured at room temperature before and after irradiation by means of optical microscopy. The observed dimensional changes of all the samples are very small for the low fluency of 1.5×1014Ar/cm2. Upon the increase of ion fluency to 1.6×1015Ar/cm2, dramatic and irreversible dimensional changes are observed and the measured relative changes in width, △b/b0, are in the range of 4.3-12.0%. The results are qualitatively discussed.

Abstract: Small strips of amorphous alloys Fe77.2Mn0.8Si9B13, Fe39Ni39V2Si12B8, Fe47Ni29V2Si6B16, and Fe40Ni40Si12B8 were irradiated below 50°K with 2.79 MeV/u Ar ions delivered from Heavy Ion Research Facility in Lanzhou (BDDRFL). The macroscopic dimensions of the samples were measured at room temperature before and after irradiation by means of optical microscopy. The observed dimensional changes of all the samples are very small for the low fluency of 1.5×1014Ar/cm2. Upon the increase of ion fluency to 1.6×1015Ar/cm2, dramatic and irreversible dimensional changes are observed and the measured relative changes in width, △b/b0, are in the range of 4.3-12.0%. The results are qualitatively discussed.
