The anti recrystallized effect attained due to the Al3Sc particles is very pronounced. For example,cold-rolled scandium-bearing aluminium alloy sheets subjected to deformation with percent reduction of 80% and more retain a fully non recrystallized structure after heating for quenching and annealing. In the case of A alloy semi-products, this structure retains up to heating to a melting temperature of 590°C
