摘要：

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 tau = 60 ns, 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 (100A/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. (C) 2002 Elsevier Science Ltd. All rights reserved.
