A method for manufacturing metal by a cold worked powdered metal forging process is disclosed. A certain amount of a powdered metal is measured out and then compacted into a briquette or other compact. The briquette is then sintered to form a preform. After sintering, the preform is then cold worked to increase its strength. After cold working, the preform is forged to form the desired part. The resultant part has improved fatigue life, surface finish, and metallurgical characteristics.
