Summary

A range of AA 2024 high strength Aluminium Alloy-Haematite MMCs were produced by extruding cast bars. Forging trials were conducted at 4400–460 °C and at a strain rate of 0.2 s−1. Solution treatment and natural ageing were carried out. Tensile tests showed significant increase in mechanical properties. The MMC with an optimum 4 % by weight of Haematite increased ultimate tensile strength by as much as 12 % & 0.2 % proof stress by 6 %. The fracture toughness KIC was not significantly affected. The Galvanostatic polarisation tests revealed addition of Haematite markedly improved corrosion resistance of the base alloy.
