6.2 Mechanism of Slip

Slip occurs on planes that have highest planer density of atoms and in the direction with highest linear density of atoms (Fig. 6.4). That is, slip occurs in directions in which the atoms are most closely packed since this requires the least amount of energy. Therefore they can slip past each other with less force. Slip flow depends upon the repetitive structure of the crystal which allows the atoms to shear away from their original neighbors. It therefore slides along the face and joins up with the atom of new crystals.
