ABSTRACT:
A method of producing a densified compact from a loose metal powder, the method comprising introducing strain into each particle of the loose metal powder to impart a residual stress to increase the potential energy level of the particles above the potential energy which the particles may have acquired during production thereof, the strain being introduced at a temperature below the recrystallization temperature thereof, and thereafter hot consolidating the loose metal powder.
