What engineering properties are likely to decline during the cold working of a metal?
*Cold rolling is a metal working process in which metal is deformed by passing it through rollers at a temperature below its recrystallization temperature. *Cold rolling increases the yield strength and hardness of a metal by introducing defects into the metal’s crystal structure. *These defects prevent further slip and can reduce the grain size of the metal, resulting in Hall-Petch hardening. *Cold rolling is a method of cold working a metal. When a metal is cold worked, microscopic defects are nucleated throughout the deformed area. These defects can be either point defects (a vacancy on the crystal lattice) or a line defect (an extra half plane of atoms jammed in a crystal). *As defects accumulate through deformation, it becomes increasingly more difficult for slip, or the movement of defects, to occur. This results in a hardening of the metal. *If enough grains split apart, a grain may split into two or more grains in order to minimize the strain energy of the system. When large gr
