Shrinkage

The contraction of metal during cooling after hot forgingSame as hot working—plastically deforming an alloy at a temperature above its recrystallization point, i.e, high enough to avoid strain hardening.. DieThe machined recess in a die that gives the forging its shape. impressions are made oversize according to precise shrinkageThe contraction of metal during cooling after hot forging. Die impressions are made oversize according to precise shrinkage scales to allow the forgings to shrink to design dimensions and tolerances. scales to allow the forgings to shrink to design dimensions and tolerances.
