040 Stee 0 0 400 600 0 0 200 400 600 Percent cold Percent cold 4. (20 points) Suppose that you work for a company that manufactures 1040 steel wire. A customer asks for 1 mm diameter 1040 steel wire with a yield strength of at least 700 MPa and a ductility of at least 12% elongation. Your warehouse is out of this material, but has a large amount of 1.5 mm diameter fully annealed 1040 steel wire, and you have access to wire drawing equipment and a heat treatment furnace. Use the attached diagram (Figure 7.19) to explain how you will produce the appropriate wire from the available material giving the diameter of the wire at each step B. (10 points) What is the load (in Newtons) that the final product wire will be able to support without failure?

    A cylindrical car component with 7 mm diameter is to be manufactured. The component is required to possess a yield strength of at least 700 MPa and an elongation to fracture of at least 11%. For this purpose, you use a cylindrical steel 1040 rod with an initial diameter of 9 mm. The percent cold work cannot exceed 40% during any single cold deformation step in order to avoid cracking. Using the diagram below, describe your manufacturing procedure for this...

    4. (a) What is cold work and its significance in material properties. (b) Briefly explain why cold-worked metals are more susceptible to corrosion than noncold-worked metals. (c) A cylindrical rod of 1040 steel originally 15.2 mm in diameter is to be cold worked by drawing; the circular cross section will be maintained during deformation. A cold-worked tensile strength in excess of 840 MPa was applied. Determine the percent cold work if the final diameter must be 10 mm. [20 pts]
