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.文件大小: 92KB

What Is Annealing 7 Types of Annealing Process …

The process of heating a metal or alloy to an appropriate temperature for a certain period of time and then slowly cooling generally with the furnace cooling is called annealing. The essence of annealing is the transformation of the pearlite after heating the steel to austenitizing. After annealing the tissue is close to that after equilibrium.
