Abstract:
Five compositions of aluminium iron bronze in the (α+β)-phase region containing 2.5 to 5 at.% Fe and 5 to 15 at.% Al have been prepared for microstructural characterization by X-ray diffraction line-profile analysis, optical and scanning electron microscopy, microhardness and magnetic susceptibility studies. The solute dependence of the defect parameters as revealed from X-ray study reflect the microstructural evolution in the deformed state especially near the α/(α+β) boundary. The influence of increased presence of Fe results in the lowering of stacking fault energy of pure Cu. Optical and scanning electron microscopy reveal the grain sizes and grain boundary structure, containing dispersed Fe-rich precipitates, Fe 3 Al. Microhardness studies of the alloys depict the cumulative influence of Al and Fe 3 Al precipitates in increasing the hardness (from 79.0 to 139.5 Kg/mm 2 ). These Fe-rich precipitates are primarily responsible for increased ferromagnetic behaviour of the materials.
