摘要
A distinct mesotexture seen in a nanocrystalline Ni-20Fe electrodeposit is described. The texture is characterized by a (001) fibre axis perpendicular to the local curvature of the nodule growth surface. Each nodule contains of the order of 10(8) grains over its growth interface. The texture shows some similarity to traditional cobblestone patterns. Similar forms of mesotextures are likely to be ubiquitous in nanocrystalline electrodeposits and can be expected to affect the homogeneity and, possibly, anisotropy of the mechanical response.
