Dislocation motion in a crystal is analogous to moving a rug over a floor by introducing a ruck on one edge. Pushing the ruck to the other edge moves the carpet by the width of the ruck. This process ...

Many important properties of metals are now understood to result from a kind of imperfection in crystal lattices that is called a dislocation. The theory is helping to transform metallurgy from an ...

The diagram shows the effect of 'sliding' an Edge (a), Screw (b), or Mixed (c) dislocation completely across a slip plane in the crystal. Each dislocation has the same effect as it moves completely ...
