Abstract

The effects of intense pulsed ion beams (IPIB) irradiation (ions of C+ and H+, accelerating voltage V = 250 kV, ion current density J = 100-200 A/cm2, pulse duration τ = 60ns, and pulse number n = 12-24) 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.
