摘要：

Bulk ordered nanocrystalline T49.4Ni50.6 alloys with a grain size of 23-31 nm were prepared using severe plastic deformation. Nanocrystalline and coarse-grained alloys were subjected to 1.5 MeV Ar+ ion irradiation at room temperature. At the same damage dose the nanocrystalline alloy retained the long-range order while the coarse-grained counterpart was amorphized. In contrast to former irradiation studies, fully dense nanocrystalline materials are used in the present study for the first time. (c) 2008 Acta Materialia Inc. Published by Elsevier Ltd.
