Abstract
The results of a transmission electron microscope study of the microstructure of splat-quenched Al-8% Fe are described in detail. Two distinct structures, zone A and zone B, are examined in as-quenched samples, and each characterized in terms of the dispersions and types of phases present. The decomposition behaviours of zone A and zone B during annealing at temperatures between 573 and 823 K (300 and 550°C) are investigated and the associated phase transformations determined. The effect on the as-quenched, and annealed, microstructures of adding either 3% Mn or 1% Zr to the alloy is described. The observed microstructures and phase transformations are correlated with micro-hardness measurements.
