ResumoAbstract 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/cm 2 , pulse duration τ =60 ns, and pulse number n =12–24) on the phase and microstructure response of Ni 3 Al-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/cm 2 ). With further increasing ion current density (150–200 A/cm 2 ), 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.
