TEXTURAL ANALYSIS OF FexZn(1–x) ALLOYS FORMED BY ELECTRODEPOSITION AND SOL-GEL TECHNIQUES
Keywords:
Fe–Zn alloy, Electrodeposition, Sol-gelAbstract
Crystallographic textural analysis of FexZn(1–x) alloys formed by electrodeposition and sol–gel techniques was done. Lattice parameters and phase structures of the alloys were elucidated and correlated to empirical composition. In electrodeposited alloy 101 pyramidal plane is dominant with ‘η’ (distorted hcp) phase structure, whereas the alloy formed under sol–gel conditions has significant 002 basal plane orientation with ‘Γ’ phase structure. HCP Lattice distortion is not observed for alloys from sol–gel method. Crystallite size and internal average strain was lower for the alloys obtained from sol–gel method. However, due to epitaxial nucleation by Zn ad-atoms and the selective precipitation of ‘η’ phase over ‘δ’ phase, the lattice orientation is more uniform and dense packed for electrodeposited alloys.
