What is a dislocation line?
What is a dislocation line? Line defects, or dislocations, are lines along which whole rows of atoms in a solid are arranged anomalously. The resulting irregularity in spacing is most severe along a line called the line of dislocation. Line defects can weaken or strengthen solids. What is a dislocation in a crystal lattice? A dislocation is a crystallographic defect or irregularity within a crystal structure. Dislocations are generated and move when a stress is applied. The motion of dislocations allows slip-plastic deformation to occur. There are two types of dislocations: edge and screw. Why do dislocation loops tend to...
