The goal of this research is to evaluate the impacts of cold working and annealing on the microstructure of copper strips, study Rockwell’s Hardness of copper strips undergoing cold working and annealing, and determine recrystallization temperature. The study shows that an increase in the temperature of annealing decreases the average hardness of the pieces of copper strips. Reduction of thickness from 0% to 10% decreases the average hardness of the copper strips. However, as the thickness reduction reaches 30%, the average hardness would start to increase and continue to increase until a 50% thickness reduction. The highest hardness is observed in the copper strips that had a 50% thickness reduction due to rolling. Overall, this shows that the hardness of a material increases as the reduction of thickness increases. The microstructures of copper strips after undergoing cold work rolling show that grains are elongated in the rolling direction. On the other hand, the microstructures of copper strips undergoing annealing show that the grains appear to grow and expand after heating. The grains' rate of growth increases as the temperature of annealing increases.
