“…2(a)-(c)), the α-Al matrix has a black contrast, and the gray and white contrast needle shaped intermetallic compounds are distributed along the grain boundaries. The mechanical properties of metals are largely determined by the size and volume fraction of grains or phases [11]. The intermetallic compound fraction of al-Zn-mg-mn alloys with various amounts of Sr addition was investigated using an image analyzer.…”

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.
