C-curves of isothermal decomposition of the solid solution of scandium in aluminum are plotted for binary Al – Sc alloys with different scandium content. It is shown that growth in the scandium content from 0.14 to 0.55% reduces the incubation period by 2 – 3 orders of magnitude and increases the rate of the decomposition by 2 orders of magnitude. The causes of the accelerated decomposition of the solid solution of scandium in aluminum are discussed.
