RE: Edge dislocation
Here is an excerpt:
Sources of dislocations[edit]
density in a material can be increased by plastic deformation by the following relationship: (****) . Since the dislocation density increases with plastic deformation, a mechanism for the creation of dislocations must be activated in the material. Three mechanisms for dislocation formation are homogeneous nucleation, grain boundary initiation, and interfaces between the lattice and the surface, precipitates, dispersed phases, or reinforcing fibers.
**** = tau (is proportional to) roh squared.
My questions:
tau ?= Dislocation density units?
roh ?= plastic deformation units?
It's OK, I'm not a student.
