Problem 5. 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. 120 70% Cu-30% Zn 100 Tensile strength 80 60 60 Yield strength 40 40 20 20 Elongation 10 20 30 40 50 60 Percent cold work Tensile strength and yield strength (ksi) Elongation percent
