Effect of Co Distribution on Plastic Deformation of Nanocrystalline Al-10.2 at.% Co Alloy

Figure 2

Stress-strain curves for the nanocrystalline pure Al (blue line), Al-Co solid solution (red line), and Al-Co alloy with the GB segregations of Co (green line). For (a, b), the deformation temperature is 300 K, while for (c, d), it is 600 K. The hydrostatic pressure in (a, c) is 0 GPa, while in (b, d), it is 6 GPa.
