Abstract
IN an earlier communication1, an account was given of an experimental examination of the behaviour of the crystal boundaries in aluminium and its alloys at temperatures near the melting point. In an extension of this work, some consideration was given to the results obtained by Achter and Smoluchowski2 in their studies of the structure and properties of grain boundaries, and it was thought desirable to construct a dislocation model for a study of grain-boundary phenomena. It was hoped that this model would also prove of use in a related investigation of the mode of deformation of the crystals of a polycrystalline mass under a rapidly applied force.
