Abstract:

The influence of Fe content on the microstructure,conductivity and corrosion resistance of AlFe alloy is tested and analyzed by SEM,EDS,electrochemistry,metallographic examination and chemical analysis.Research results indicate that Fe forms second phase in Al matrix.The increase of Fe content in Al matrix yields more second phases with no evident change of morphology and scale.On macroscopic scale,the hardness increases while the conductivity decreases.Moreover,the second phase FeAl3 of AlFe alloy leads to better corrosion resistance.

Key words: Al Fe aluminum alloy;Fe content;microscopic structure;conductivity
