“…Nickel films were deposited onto an amorphous substrate applying electrochemical deposition from a Watts bath with different amounts of the organic additive 2-butyne-1,4-diol and varying current densities; for details on electrodeposition the reader is referred to Alimadadi et al (2012). The thin amorphous substrate layer was deposited onto a copper sheet prior to the deposition of the nickel films.…”

Nanocrystalline Ni thin films have been produced by direct current electrodeposition with different additives and current density in order to obtain h100i, h111i and h211i major fiber textures. The dislocation density, the Burgers vector population and the coherently scattering domain size distribution are determined by high-resolution X-ray diffraction line profile analysis. The substructure parameters are correlated with the strength of the films by using the combined Taylor and Hall-Petch relations. The convolutional multiple whole profile method is used to obtain the substructure parameters in the different coexisting texture components. A strong variation of the dislocation density is observed as a function of the deposition conditions.

An experimental evidence of deformation twinning in coarse-grained aluminium is presented for the first time using electron backscatter diffraction technique. This phenomenon occurs when using a novel method of severe plastic deformation referred to as dynamic channel angular pressing. A pressing die had two channels of equal cross-sections intersecting at an angle of 90°. A special gun accelerated the sample up to the speed of 100 m s -1 and directed it into the die. As a result, the strain rate was about 10 5 s -1. Twin-oriented mesobands of 3 to 20 μm in width appear predominantly near grain boundaries after deformation. Crystallographic characteristics of the mesobands formed in two different grains were examined in detail. Analysis of a deviation of their misorientations from the ideal twin misorientation showed that the first mesoband family could be formed at an early stage of the first pass of the dynamic channel angular pressing, while the second family -at a later stage. The mesobands were suggested to form by successive nucleation and coalescence of microscopic twins during the shear localization. Results have shown that in aluminum, which is characterized by higher stacking fault energy and higher dislocation mobility, deformation twinning occurs only under high strain-rate dynamic deformation.

“…At a distance of 4 µm from the interface, the texture remains weak, although various components evolve. Further away from the interface a major <210> has developed, accompanied by two minor components, <542> and <711>, both originating from twinning of <210> [22]. This texture remains on further growth of the electrodeposit.…”

Quantitative crystallographic texture analysis by XRD was supplemented by microtexture analysis applying EBSD. While XRD results correspond to absorption-weighted averages over the top part of the layer, EBSD on the cross section allowed studying the texture evolution as a function of distance to the substrate. Although layer growth started on amorphous substrates, implying that nucleation occurs unbiased by the substrate, often relatively strong fiber textures develop already at the early stage of growth. These fiber textures can further develop into other preferred fiber axis further away from the substrate. The experimental results demonstrate that already in an early stage of deposition there are major differences in the developing textures. The evolution of the substrate-adjacent textures into the texture of thick layers depends strongly on the deposition conditions.
