“…The corrosion resistance of the aluminum sheets is discussed by measuring the dynamic potential polarization curves and electrochemical impedance spectroscopy (EIS) curves in 3.5 wt% NaCl solution using electrochemical workstation at scan rate of 100 ms and the voltage range of −1 to 2 V, and the corrosion current ( I corr ) can be determined by back-propagating the corrosion voltage ( E corr ) and the corrosion rate ( V corr , mm a −1 ) is calculated according to eqn (1). 38,39 V corr = 22.85 × I corr …”

“…aluminum alloys are widely used in the fields of electrical materials, electrical conductors, transmission lines, communication cables, and automotive wires due to their high conductivity, low cost, good formability, low density and corrosion resistance. The high conductivity al alloys used in these various parts require high conductivity and mechanical properties [1][2][3][4]. For electrical products, if heat retrieving characteristics are not secured, life expectancy and efficiency rapidly drop, so heat removal efficiency is needed for elevated output.…”

This study investigated the improvement in the electrical conductivity and mechanical properties obtained by adjusting the amount of the Sr addition to the Al-Zn-Mg-Mn alloy. The addition of Sr formed an intermetallic compounds, and the volume fraction of the intermetallic compounds increased with increasing Sr content. As the amount of Sr added increased from 0 to 1.0 wt%, the electrical conductivity of the extruded alloy decreased to 48.9, 45.2 and 42.5% IACS. As the addition amount of Sr increased, the average grain size of the rolled alloy decreased to 55.5, 53.1 and 42.3 μm. And, the ultimate tensile strength increased to 195, 212 and 216 MPa.

The AlSi10Mg alloy fabricated by laser powder bed fusion was subjected to isochronal annealing for 2h at temperatures in the range of 100–520 °C. Recovery and grain growth of the annealed samples were investigated by combining EBSD and in situ TEM techniques. A bimodal grain size distribution with grain sizes of 0.9 μm and 2.3 μm was developed in the initial sample, where large grains were found in the interiors of melt pools and most of small grains were distributed along melt pool boundaries. In-situ TEM investigations revealed that nucleation that occurs at the melt pool boundaries is as a consequence of migration of high angle boundaries during annealing. A slight increase in grain sizes was discovered during high-temperature heat treatment, indicating the remarkable thermal stability of the alloy compared to conventional cast Al-Si alloys. This is explained by the fact that the stable eutectic Si structure, which was originally formed during rapid solidification, can effectively retard grain boundary migration during recrystallization.
