Room‐temperature uniaxial compressions of 900‐nm‐diameter aluminum bi‐crystals, each containing a high‐angle grain boundary with a plane normal inclined at 24° to the loading direction, revealed frictional sliding along the boundary plane to be the dominant deformation mechanism. The top crystallite...
