| Outline of Final Research Achievements |
The purpose of this study was to demonstrate the deformation mechanism of bulk nanocrystalline Fe-Ni alloys with high strength and high ductility. Micro-XRD analysis of the bulk nanocrystalline alloys after tensile tests was conducted. Micro-XRD analysis showed that the normalized intensity of the (111) peak decreased while that of the (200) peak increased. In contrast, there was no change in the FWHM values of (111) and (200) peaks.
