ABSTRACT:
A novel and improved method of forging preselected recessed surfaces in a member is disclosed which comprises the steps of adding a suitable lubricant material to at least a slave or primary preform member wherein the lubricant material is sufficient to prevent welding between the noted preforms during the forging operation. Moreover, the method envisions the step of joining the slave preform to the primary body preform member, followed by forging the joined together preforms such that the primary preform member is deformed to an extent generally complementary to a portion of the configuration of the slave preform, such that the forged primary preform has formed therein a shaped recess generally complementary to at least a portion of the configuration of the slave preform. It is contemplated that the forged slave and primary preforms are quenched subsequent to forging. Thereafter, the method contemplates removing the quenched slave preform from the primary preform.
