“How does plastic deformation in a material affect the internal defects?”
All physical materials have defects within their crystal structure. Furthermore, plastic deformations can cause the internal structure of a material to shift. So what happens when a plastic deformation is applied to a material with edge dislocations? Well, let’s use our scientific mindset to think about it. We know that these edge dislocations represent an absence of atoms along a chain. We also know that applying plastic deformations will cause a plane of atoms to move in the direction of the force. So logically, wouldn’t this plastic deformation cause the edge deformation to move within the lattice? This is the fundamental idea behind a phenomenon in Materials Science and Engineering known as a slip and can be used to characterize the internal movement of atoms.
