Abstract: A cylindrical metal part is formed by filling a metallic jacket with a powdered metal material and subjecting the metallic jacket to heat and pressure to cause the powdered metal material to form a unitary metal part. The small grain size of the metal material forming the unitary metal part will then allow for ultrasonic testing to be performed to detect voids and imperfections having very small dimensions. The ultrasonic testing can be performed through the metallic jacket, or after the metallic jacket has been removed from the unitary metal part. Additional forging steps may be performed to form shaped protrusions on the exterior of the metal part.
