The effect of homogenizing regime is studied for continuously cast ingots of alloy of the Al – Zn – Mg – Sc – Zr system on the structure and properties of extruded strips and cold-rolled sheets prepared from them. It is established that the properties of these semiproducts in a thermally strengthened condition depend little on homogenizing regime as a result of constancy of their grain structure, which remains unrecrystallized (polygonized) after heating for hardening. Breakdown of transition metal solid solution present in the alloy, occurring during ingot homogenization affects the recrystallization temperature and kinetics, and also the stability of zinc and magnesium solid solution in aluminum in the semiproducts obtained from ingots.
