Cold Working a Copper Alloy
Copper alloy (Cartridge Brass), 70 Cu- 30-Zn, and cold working them to 10%, 20%, 30%, and 40%. We will take all the point from each hardness and plot them on a hardness vs % Cold work graph. We will create to plots, one that calculates the %Cold work using area, and the other using thickness. Finally, we will compare each plot to

Work Hardening and Annealing of Copper
Copper has a cubic crystal structure (Face Centered Cubic) that gives it high ductility. Bending the copper causes work hardening (or strain hardening) because working or straining the copper introduces defects, known as dislocations, into the structure. These defects interfere with further deformation, making the copper harder and stronger, thus
