The antirecrystallized effect attained due to theAl3Sc particles is very pronounced. For example,cold-rolled scandium-bearing aluminium alloysheets subjected to deformation with percent reductionof 80% and more retain a fully nonrecrystallized structureafter heating for quenching and annealing. In thecase of 1970 (Al–5.2% Zn–1.8% Mg–0.4% Cu–Sc–Zr–Mn–Ti) alloy semiproducts, this structure retainsup to heating to a melting temperature of 590°C [
