Effect of a Small Addition of Scandium on the Phase Composition and Properties of Wrought Al–Cu–Er–Mg–Mn–Zr Alloy

  • Published:
Metallurgist Aims and scope

The effect of 0.07% Sc on t he phase composition and properties of a novel wrought Al–3.7Cu–2.3Er–0.8Mg–0.7Mn–0.2Zr–0.1Ti–0.15Fe–0.15Si alloy with a decreased content of alloying elements was investigated. The ingot microstructure contains a solid solution of aluminum along with Al3Er, Al25Cu4Mn2Er , and Al8(Cu, Mn, Fe)4 Er phases. During crystallization, scandium becomes distributed between the aluminum solid solution and Al3Er phase. Approximately 0.8% Sc is dissolved in the Al3Er phase. In the studied scandium-containing alloy, the softening rate during annealing of the rolled sheets is lower, which is caused by an inhibition of the polygonization process due to higher density of dispersoids formed during homogenizing annealing of the ingots. The alloy has a higher onset temperature of recrystallization, since after an hour-long annealing at 400°C, it still contained non-recrystallized grains, while scandium-free alloy was completely recrystallized. The hardness of the 0.07% Sc- containing alloy with a lower content of the basic alloying elements is higher by 9–14 HV.
