text: The key difference between edge and screw dislocation is that the edge dislocation is a type of line defect that occurs when an extra half-plane of atoms exists in the middle of the crystal lattice whereas the screw dislocation is also a type of line defect but it occurs when the planes of atoms in the crystal lattice trace a helical path around the dislocation line.
text: Screw dislocation is another type of line defect in which the defect occurs when the planes of atoms in the crystal lattice trace a helical path around the dislocation line.
