Production and Characterization of Aluminum Iron Powder Composites with Ferromagnetic Properties
Composites made from compacted powders blends of Al with different Fe contents were produced and characterised with respect to mechanical and induction heating properties. Mechanical spectroscopy and hardness measurements were employed to follow the evolution of Young modulus and internal friction after ageing. It was found that above a critical iron content (>30% of the volume) a percolation network of Fe grains is obtained inside the specimen and the induction heating characteristics become comparable with those of ferritic steel samples.
