Abstract

Preforms of Ni-Mo alloy steel have been deformed at 1130°C in lubricated closed dies, the ratio D0/D, where D0 is the die diameter and D the initial preform diameter, being varied between 1·0 and 1·37. Both the high-speed Petro-Forge and a crank press were used, and parameters such as forging load, energy, and density during the forging operation were measured.

The stages by which densification proceeds are considered, together with their influence on preform design.
