Fig.4 Effects of the microstructural parameters on the mechanical properties of heterogeneous structures (a, b) effects of size of coarse and fine grains on the back stress hardening[38] (c) schematic of interface affected zone in the laminate structure[26] (d) effect of thickness of interface affected zone on the back stress[26] (e) volume fraction of fine grains on the stress-strain curves[50] (CR—cold rolling, HS—heterogeneous structured, CG—coarse grain, YS—yield strength, UE—uniform elongation, UTS—ultimate tensile strength, EFT—elongation to fracture) (f) back stress[50] (σh—HDI stress, σeff—effective stress obtained from the loading-unloading-reloading test)
