Abstract

The mechanical response of ion irradiated metallic glass specimens with nominal composition of Ti₄₀Cu₃₂Pd₁₄Zr ₁₀Sn₂Si₂ was investigated by nanoindentation. Surfaces of specimens fabricated by the melt spinning process were irradiated with 4 MeV Fe²⁺ ions at 25 °C over a range of fluences from 1 × 10¹² to 1 × 10¹⁵ ions/cm². Irradiations were also performed at temperatures up to 300 °C. Nanoindentation experiments were performed to obtain values of reduced elastic modulus and hardness and to investigate the material's shear band behavior. Irradiation was found to result in a lower reduced elastic modulus and hardness, however was found to increase homogeneous deformation by suppression of shear band activity.
