Abstract
The mechanism by which a fragmented microstructure is formed when there are large degrees of deformation which occur on the surface of a metal during friction, is considered. It is shown that size of the fragments under these conditions is a minimum and is related to the dislocation density, reaching a critical value in an extremely deformed state, above which the interdislocation interaction forces are greater than the internalfriction forces.
