Abstract

Strengthening of aluminum alloys of the Al-Sc system in ingots due to decomposition of the solid solution of scandium in aluminum is studied as a function of the content of scandium (varied from 0.14 to 0.55%), of the presence of Zr, Ti, Hf, V, and Co additives at the same content of scandium (0.2%), of the Sc/Zr proportion at the same total content of Sc + Zr, and as a function of iron and silicon admixtures.
