References


Forging is one of the oldest metalworking processes known to man.As early as 2000 B.C.,forging was used to produce weapons,implements,and jewelry.The process was performed by hand using simple hammers.
Hot forging is defined as the controlled,plastic deformation or working of metals into predetermined shapes by means of pressure or impact blows,or a combination of both.In hot forging,this plastic deformation is performed above the recrystallization temperature to prevent strain harding of the metal.
During the deformation process,the crystalline structure of the base metal is refined and any nonmetallic or alloy segregation is properly oriented.In bar stock,the grain flow is only in one direction.When the contour of the part is changed,the grain flow lines are cut,rendering the metal more susceptible to fatigue and stress corrosion.Hot forging develops the grain flow so that it follows the outline of the part being formed.The directional alignment of the grains or fibers helps increase strength,ductility,and resistance to impact and fatigue in the metal.
Deformation is affected by the stress inherent in the metal,the microstructural characteristics of the starting material,the temperature at which the deformation occurs,the rate at which the deformation occurs,and the frictional restraint between the material being forged and the die surface.
