Line defects in crystalline solids
These type of defects are also called dislocations or line defects (1-D). They are caused when a portion of the crystal slides or slips relative to another. the plane in which the dislocation moves
through the lattice is called the slip plane.
The result is a distorted region along a line AB also called the dislocation line. There are three possible cases:
1. atoms are displaced ^ to AB ® edge dislocation
2. atoms are displaced || to AB ® screw dislocation
3. atoms are displaced at other angles ® mixed dislocation:
