a cylindrical rod of 1040 steel originally 11.4 mm in diameter is to be cold worked by drawing until the diameter of 8.9 mm. a cold-worked tensile strength in excess of 800 mpa and a ductility of at least 10%el are desired. based on the plots below, 1) if you directly draw the rod from 11.4 mm to 8.9 mm, what will be the amount of cold work? can you satisfy the requirements for the mechanical properties? 2) to satisfy the requirements for the mechanical properties, what is the range of your cold work? 3) if you take the first draw at 20%cw, what will be the amount of cold work in the second draw? 4) what process do you need to do between the two cold works? explain how this may be accomplished.
