At the identical time, the shape on the stress train curves for the Al Ni alloy in as-cast state and soon after HPT differs less clearly. The pressure train curves of all cast alloys in the uniform deformation stage corresponded to the Hollomon’s Equation (two): S = K en (two)exactly where: S and e are true stress and strain, respectively; n–strain hardening exponent. So, for the Al Ce alloy, the uniform strain stage is described by the equation S = 376.9 e0.42 (determination coefficient R2 = 0.96), for the Al0 La alloy–S = 485.eight e0.43 (R2 = 0.96), and for the Al Ni alloy–S = 935.5 e0.64 (R2 = 0.99). Nonetheless, the stressstrain curves on the HPT-processed alloys are a lot more complicated. The strain hardening exponent at the uniform deformation stage changes, namely, it decreases with an increase within the degree of strain. Simplistically, a single can divide the uniform deformation stage into two stages and each approximate by the Hollomon’s equation. So, for the Al Ce alloy, the initial section of uniform strain stage is described by the equation S1 = 2295 e0.55 (R2 = 0.97), along with the final one–S2 = 761.5 e0.14 (R2 = 0.96). For the Al0 La alloy, respectively, S1 = 1286.1 e0.42 (R2 = 0.96) and S2 = 495.eight e0.09 (R2 = 0.98). For the Al Ni alloy, respectively, S1 = 4538.6 e0.79 (R2 = 0.99) and S2 = 1329.9 e0.28 (R2 = 0.95).Supplies 2021, 14,11 ofIt is identified that metallic nanostructured components obtained by the SPD approaches are thermally unstable, particularly metals with a low melting point, like aluminum alloys [32].
