3XPL@!N THE PROCESS @ND PROVIDE EXAMPLES FORMING OPERATIONS 1. Forging is mechanically working or deforming a single piece of a usually hot metal; this may be accomplished by the application of successive blows or by continuous squeezing. 2. Rolling, the most widely used deformation process, consists of passing a piece of metal between two rolls; a reduction in thickness results from compressive stresses exerted by the rolls. 3. Extrusion, a bar of metal is forced through a die orifice by a compressive force that is applied to a ram; the extruded piece that emerges has the desired shape and a reduced cross-sectional area. 4. Drawing is the pulling of a metal piece through a die having a tapered bore by means of a tensile force that is applied on the exit side.

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.
