Transmission Electron Microscopy: (a) STEM image from Al0.3CoCrFeMnNi + 0% Y2O3 showing the nano-grains formed by the SPS process. (b) STEM image from Al0.3CoCrFeMnNi + 3% Y2O3 shows the nano-grains along with the dark contrast dispersoids. Inset on top shows the SADP from Cr-carbide, and that on the bottom shows SADP from fcc + B2 phases.
