Deformation and recrystallization textures in nanocrystalline nickel with average grain size of 20 nm were investigated using X-ray diffraction, electron microscopy and differential scanning calorimetry. The deformation behaviour of nanocrystalline nickel is quite complicated due to intervention of other deformation mechanisms like grain boundary sliding and restoration mechanisms like grain growth and grain rotation to dislocation mediated slip. Recrystallization studies carried out on the deformed nanocrystalline nickel showed that the deformation texture was retained during low temperature annealing (300°C), while at higher temperature (1000°C), the texture got randomised. The exact mechanism of texture formation during deformation and recrystallization has been discussed.
