Ml. Kharakterova et al., EFFECT OF SCANDIUM AND ZIRCONIUM ON STRUCTURE AND AGE-HARDENING OF THE AL-MG-SI ALLOYS, Russian metallurgy. Metally, (1), 1997, pp. 104-109
The effects of scandium and zirconium on the structure and age hardeni
ng of cast and wrought Al-Mg-Si alloys were studied, The simultaneous
additions of scandium and zirconium increase strength and lead to the
formation of fine eutectic in cast alloys and nonrecrystallized struct
ure in wrought alloys. The reasons for this effect are discussed.
