From Solid to Solid. Mechanics of Chemical Transformations

... to this rule: their perfection is disrupted by defects . There are three types of defects: surface defects such as crystal faces, grain boundaries, interface boundaries; linear defects (dislocations); and point defects (interstitial atoms, etc.). Plastic deformation of solids is caused by the movement of dislocations, which can be imagined as a broken edge of an atomic half-plane inside a crystal. The most efficient movement mechanism is dislocation sliding i.e. movement in the direction perpendicular ...
