Diameter Reduction Procedure Problem A cylindrical rod of brass originally 10 mm ( 0.39 in ) 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 380 MPa (
55,000\psi
) and a ductility of at least 15 %EL are desired. Furthermore, the final diameter must be
7.5\deg mm
( 0.30 in ). Explain how this may be accomplished.
