Abstract
The microstructure of Fe films electrodeposited onto from and electrolytes was examined by X-ray and electron diffraction. Symmetrical X-Ray diffraction from films deposited from chloride solutions indicates a dominant (001) texture with the presence of additional minority orientations. In contrast, deposition from an ammonium sulfate electrolyte yields films that only exhibit (001) scattering in the geometry. Transmission electron microscopy (TEM) cross-sectional images of films grown in chloride solutions reveal intermittent cube-on-cube epitaxy that is also evident in plan view TEM dark field images. Interestingly, X-ray pole figure measurements for all specimens examined reveal an additional (221) orientation that is undetectable by symmetric diffraction. The (221) oriented material most likely derives from twinning of (001) oriented grains during growth.
