**Title: Understanding Dislocations in Crystalline Materials** 3. **Task Overview**: Sketch and compare edge and screw dislocations, highlighting the primary differences between them. **Explanation**: - **Edge Dislocation**: - Involves an extra half-plane of atoms inserted in a crystal structure. - Visual Representation: Typically depicted as a straight line (dislocation line) where half of the atomic planes terminate. - Stress Field: Perpendicular to the dislocation line. - Properties: Edge dislocations move parallel to the applied stress. - **Screw Dislocation**: - Characterized by a helical ramp resulting from shear stress. - Visual Representation: Spiral structure resembling a screw, twisting along the dislocation line. - Stress Field: Parallel to the dislocation line. - Properties: Screw dislocations move perpendicular to the applied stress. **Comparison**: - **Direction of Movement**: Edge dislocations move parallel to stress, while screw dislocations move perpendicular. - **Stress Orientation**: Edge has a perpendicular stress field, screw has a parallel stress field. Understanding these dislocations and their behaviors is crucial for studying the mechanical properties and deformation of materials.
