WebMar 22, 2024 · (1) The mechanical properties of forgings in the axial and radial directions are more consistent compared to rolled products. This means that forgings have a much higher degree of isotropy, resulting in … Hot forging is the plastic deformation of metal at a temperature and strain rate such that recrystallization occurs simultaneously with deformation, thus avoiding strain hardening. For this to occur, high workpiece temperature (matching the metal’s recrystallization temperature) must be attained … See more Cold forging deforms metal while it is below its recrystallization point. Cold forging is generally preferred when the metal is already a soft metal, like aluminum. This … See more
WebAxisymmetric forging — A forging where metal flow, during deformation, is predominately in a direction away from a common axis in a radial direction. Backward extrusion — Forcing metal to flow in a direction opposite to the motion of a punch or die.
