Abstract
IT has been shown by Kê1 that differences in the mechanical properties of specimens of aluminium with large and small crystal sizes can be accounted for by assuming that the crystal boundaries behave as viscous liquids. Quantitative experimental evidence of the relative movement of neighbouring crystals in a manner consistent with this hypothesis has so far been lacking.
