Abstract

Alloys of composition Sn-8.5Sb-5.5Cu (in atomic percent) were rapidly solidified by a melt-spinning technique. The samples were irradiated at room temperature with GeV uranium ions of fluences between 9 × 10⁸ and 9 × 10¹¹ ions cm^-2. X-ray diffraction analysis revealed the formation of a new-phase Cu₁₁Sb₃ as well as a reduction in the axial ratio (c/a) of the matrix (β-Sn) indicating the regular re-arrangement of atoms. Scanning force microscopy showed no surface topographic changes with the ion fluence. The mechanical properties (Young's modulus and hardness) of the irradiated alloys were studied as a function of ion fluence. The radiation-annealing process is discussed in terms of the evolution of both resistivity and hardness as a function of ion fluence.
