Surface modification of Ni3Al-based alloy IC6 with intense pulsed ion beams

The effects of intense pulsed ion beams (IPIB) irradiation (ions of C+ and H+, accelerating voltage V ¼ 250 kV, ion current density J ¼ 1002200 A/cm2, pulse duration t ¼ 60 ns, and pulse number n ¼ 12224) on the phase and microstructure response of Ni3Al-based alloy IC6 have been studied. It is shown that the deformation texture can be formed on the surface layer of target under IPIB irradiation with a low current density (100 A/cm2). With further increasing ion current density (150–200 A/cm2), the formation of amorphous and new phases occurs. A higher density of dislocations can be observed in the irradiated specimen compared to the unirradiated specimen.
