Ankerson and Grepper, the intention of my post was to explain to Ken the term work hardening in an understandable but physically correct way. It explains the processes in steel wire Mike is bending in one of his videos.
Hopefully everybody here knows that a paper clip is made of low carbon steel and so could not be confused by the quoted classical experiment.
I am aware that the work hardening is applied to non-brittle metals and for this reason I have not mentioned knife blade or burr in my post.
I am afraid that our understanding of burr forming processes is still not complete. I am wondering if the microscopic structure and properties of a sub-micron burr are the same as those of the bulk blade material’s.
