Enhanced ion irradiation resistance of bulk nanocrystalline TiNi alloy

Bulk ordered nanocrystalline Ti 49.4Ni 50.6 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 th...

Zusammenfassung:Bulk ordered nanocrystalline Ti 49.4Ni 50.6 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.
