- Which of the following is true about open die forging process? O Forged pieces have accurate dimensions therefore there is usually no need for additional finishing operations such as heat treatment or machining. O Forged pieces have outstanding grain structure and the best combination of mechanical properties. O Forging is carried out at temperature above re-crystallization temperature Forged pieces are small in size since the forging process is incapable of doing large components such as turbine shafts.arrow_forwardWhich would normally have the highest percentage elongation at break, 0.1% carbon steel or aluminium alloy?arrow_forwardExample 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.
