In recent years scandium has attracted the attention of researchers as
an alloying component of aluminum alloys. industrial compositions of
scandium-alloyed aluminum alloys have been developed with consideratio
n of its various positive effects on the structure and properties of a
luminum. The results of an investigation of the kinetics of decomposit
ion of a solid solution of scandium in aluminum are analyzed and gener
alized. C-curves of the decomposition are presented for aluminum alloy
s with different contents of Sc, Si, Fe, Mn, Zn.
