Abstract:

In Technical Report WVT-TR-75054 on cold rotary forging of rifling into a thin-wall gun tube, it was stated that the yield strength of the forged material increased in the longitudinal direction, while a recoverable loss was observed in the tangential hoop direction. A recently obtained metallographic study of the same material suggests a potential improvement in fatigue life and or fracture toughness of the material, attained in that earlier work but overlooked at the time.
