Question
Starting with a 2-inch diameter rod of brass, we would like to process 0.2-inch diameter rods that possess minimum yield strength of 40 ksi and a minimum elongation to fracture of 40%, (see the following figure). Design a process that achieves that.

Hot extrusion to convert into smaller diametr
Cold extrusion to further elongate
Annealing for increasing the ductility
Heat treatment for increasing strength
Cold working for imcreasing fracture toughness
