Work Hardening and Annealing of Copper

Experimental process 1. Prepare lengths of copper wire, 6 to 10 inches long, or tubing, 1 to 1.5 ft in length. 2. Ask selected class members to slowly bend the copper—careful not to cause crimping. 3. Once bent, ask another class member to unbend the copper. 4. Discuss why the copper cannot be fully unbent due to work hardening. 5.

Work hardening - Wikipedia

Work hardening, also known as strain hardening, is the strengthening of a metal or polymer by plastic deformation.Work hardening may be desirable, undesirable, or inconsequential, depending on the context. This strengthening occurs because of dislocation movements and dislocation generation within the crystal structure of the material. Many non-brittle metals with a reasonably high melting ...
