Two SG-7.5-10 electric-resistance furnaces were employed to heat the precursor melts.The#1 electric-resistance furnace was used to melt Al-Zn11.2-Mg5-Cu3 alloy at 720°C.Then 1%C2Cl6 was added into the melt for refinement.The#2 electricresistance furnace was utilized to melt pure Al at 760°C.Furthermore,pure Al(660°C)was poured into the Al-Zn11.2-Mg5-Cu3 alloy(620°C),and the two melts were then mixed quickly by stirring.When the temperature of the alloy dropped to 637°C,the mixed melt was poured into a permanent mold(preheated at 200°C)to obtain aΦ15 mm×150 mm cylindrical ingot.Figure 1 shows the controlled diffusion solidification(CDS)casting process.
