The purpose of this experiment is to determine the increase in hardness of an annealed (heat treated) copper sheet after it is passed through a rolling mill. The rolling mill reduces the thickness of the copper sheet by exerting compressive stress. This is an example of cold working, as the deformation of the copper sheet is performed at a temperature below that at which recrystallization occurs.
