“…Figure 4 demonstrates that the XTM technique can provide detailed microstructural information based on the density of different phases of the alloy. Air or void spaces appear in black, the aluminum matrix is represented by gray, while eutectic phases that contain heavier elements, for instance Al 2 CuMg (S-phase), Al 2 Mg 3 Zn 3 (T-phase) and MgZn 2 (M-phase), [17,18] appear as lighter gray.…”

“…Although the KWN model has been successfully applied to different aluminium alloys (Myhr et al, 2001;Robson, 2004a), there are no reports of application to casting aluminium alloys. The present modelling work is the first time that KWN model has been applied to the casting aluminium alloys A356 and A357 for different ageing temperatures and compared with the experimental data.…”

“…And then a strength model is used to evaluate the resulting change in hardness or yield strength at room temperature by taking into account contributions from lattice resistance, solid solution hardening and precipitation hardening. Though the KWN model has been developed for a few decades and successfully applied to a number of aluminium alloy systems, such as 2xxx, 6xxx and 7xxx (Myhr & Grong, 2000;Myhr et al, 2001;Robson, 2004a;Robson, 2004b) , however, most of modelling work has been focused on the wrought aluminium alloys and none modelling work has been applied to the casting aluminium alloys. In the present work, the KWN model has been for the first time applied to the casting aluminium alloys A356 and A357.…”

“…In the early 21 st century, some wrought aluminum alloys with very _______________________ high Zn content higher than 8.4wt%, such as AA7136, AA7095, AA7056, were registered as international designation successively, aims to replace the ultra-high strength AA7055 alloy for aerospace applications [5,6]. It is well known that homogenization process is very important for high alloying elements content 7xxx series aluminum alloys, because the microsegreation of Zn,Cu, and Mg elements and coarse intermetallic particles results in poor comprehensive properties [7,8]. Furthermore, the two-stage homogenization is widely known as not only dissolving the intermetallic particles into the aluminum matrix, but also controlling ideally the precipitation of Al 3 Zr dispersoids in the wrought 7xxx series aluminum alloys with addition of zirconium [6,7].…”

However, the study on microstructure in as-cast Al-ZnMg-Cu aluminum alloy with high Zn-containing (>9wt%) and its evolution during homogenization is still very limited.…”
