These properties in the alloy with 0.4 wt.% Mg and 0.2 wt.% Zr are achieved through the formation of ultrafine-grained microstructure (UFG) by thermomechanical treatment (TMT), including annealing, severe plastic deformation (SPD) via equal channel angular pressing-Conform (ECAP-C) followed by cold drawing. The mechanical strength is enhanced by the formation of ultrafine grains during ECAP-C and their additional refinement through cold drawing. Also, ECAP-C and drawing result in the material strengthening due to increased dislocation density. The annealing of the alloy prior to SPD is used to provide a good heat resistance and high electrical conductivity via formation of nanoscaleAl3Zr metastable precipitates and, correspondingly decreasing the concentration of Zr atoms in the Al solid solution.",

The mechanical strength is enhanced by the formation of ultrafine grains during ECAP-C and their additional refinement through cold drawing. Also, ECAP-C and drawing result in the material strengthening due to increased dislocation density. The annealing of the alloy prior to SPD is used to provide a good heat resistance and high electrical conductivity via formation of nanoscaleAl3Zr metastable precipitates and, correspondingly decreasing the concentration of Zr atoms in the Al solid solution.
