The texture evolution accompanied by grain growth was investigated in a nanocrystalline Fe-78wt%Ni alloy, namely permalloy fabricated by using an electrodeposition method. The as-deposited specimen revealed a strong //ND and a weak //ND fibre-type textures. Grain growth took place during annealing beyond 370∞C and resulted in the texture change such that the //ND fibre strongly developed at the expense of the //ND fibre. It was observed using orientation image microscopy (OIM) that the //ND oriented grains abnormally grew in the early stages of grain growth. The relationship between the texture evolution and the microstructural change during annealing is interpreted and discussed in terms of the orientation dependency of grain growth
