| dc.description.abstract | An aluminum alloy with a chemical composition of Al-6%Mg-0.35%Mn-0.2%Sc- 0.08%Zr-0.07%Cr (in wt.) and an initial grain size of ~22 μm was subjected to equal-channel angular pressing (ECAP) at 593 К up to a total strain of ~12. Extensive grain refinement provided the formation of fully recrystallized structure with an average grain size of -0.6 μm. The mechanical properties of the alloy in two different structural conditions were examined at temperatures ranging from 77 to 293 K. It was shown that ECAP highly enhanced the strength, ductility and fracture toughness of the material over the wide temperature interval. Positive effect of grain refinement tends to increase with decreasing temperature due to suppression of brittle intergranular fracture | ru |
