  • Published:
Russian Metallurgy (Metally) Aims and scope

Abstract

The structure and the electrical and mechanical properties of Al-Mg-0.22 wt % Sc-0.15 wt % Zr alloys with various magnesium contents (0, 1.5, 4.5 wt %) are experimentally studied during the decomposition of the solid solution of scandium and zirconium in the states after solidification from a melt (cast ingots) and after subsequent multicycle equal-channel angular pressing (microcrystalline structure). The dependences of electrical resistivity ρ, microhardness HV, macroelasticity limit σ0, and yield strength σy on the annealing temperature and time are analyzed.
