Dislocation

Dislocation is a type of physical deformation in which the normal crystal lattice structure of a material is broken down, usually due to an applied external force. This can happen in both crystalline and non-crystalline materials, and can lead to a permanent change in the material’s structure. Dislocation can be caused by various factors, including mechanical and thermal stresses, as well as external forces like shearing, bending, and stretching. In a crystalline material, dislocations can cause a decrease in the material’s strength, an increase in its electrical conductivity, and other changes in its physical properties. In non-crystalline materials, dislocations can cause a decrease in the material’s mechanical strength, as well as a decrease in its optical and electrical properties.
