Role of Small Addition of Sc and Zr in Clustering and Precipitation Phenomena Induced in AA7075

A detailed characterization of phase transformations in the heat-treated commercial 7075 aluminum alloys without/with low Sc–Zr addition was carried out. Mechanical and electrical properties, thermal and corrosion behavior were compared to the microstructure development. The eutectic phase consists...
