Schematic illustration of the strengthening mechanism. (a) Summary of the strengthening contributions acting in the present Al alloys. All values in the figure are the nanohardness taken from the bulk samples. (b) GB strengthening of NC fcc-Al. (c) Confining effect of NC fcc-Al on the strength of intermetallics. (d) Size effect for the nanometric intermetallics. Red stars represent the situations corresponding to the present Al alloys. τ0 is the shear yield stress under pure shear.
