Zusammenfassung: | <jats:p>The CSIR rheocasting system was successfully used to produce high pressure die cast plates of medium-strength, weldable, wrought Al-Zn-Mg alloy 7017. A solution treatment at 450oC for 5 h leads to insufficient dissolution of Mg and Zn, resulting in inadequate T6 mechanical properties after artificial aging. However, a solution treatment at 470oC for 5 h, followed by water quenching and artificial aging at 120oC for 24 h results in tensile properties comparable to those of wrought alloy 7017 plate and extrusions. The alloy also shows a strong room temperature aging response, making it ideal to be used after welding without any further heat treatment.</jats:p> |
