- Which property, brittleness or ductility, will let a metal deform without breaking? Why?Why is heat treatment typically an integral part of the process flow for bulk deformation of metal?.Example Problem-2 A cylindrical rod of non cold-worked brass having an initial diameter of 6.4 mm (0.25 in.) is to be cold worked by drawing such that the cross-sectional area is reduced. It is required to have a cold-worked yield strength of at least 345 Mpa (50,000 psi) and a ductility in excess of 20%EL; in addition, a final diameter of 5.1 mm (0.20 in.) is necessary. Describe the solution.
- A cylindrical brass rod with a minimum tensile strength of 450 MPa, a ductility of at least 13% EL (elongation), and a final diameter of 12.7mm is required. You have in your inventory some 19.0mm diameter brass stock that has been cold worked to 35%. Assuming that the cross section of the rod is still circular after being cold worked, and that brass experiences cracking at 65% CW, describe the necessary working steps in order to achieve the final product. Take the expression for % cold work to be = (Ao - Af)/ Ao x 100%, where Ao and Af are the original and final circular cross-sectional areas of the rod.In cold working, the metals can be deformed permanently after applying the forming forces. Select one: True FalseThe same alloy is used to fabricate two different components, both of which result in identical mechanical properties. Cold working yields a microstructure with a much higher incidence of symmetrical grain boundaries for Component 1 as compared with that of Component 2.
