  • Residual stress reduction of processed DU alloy rods
    Patent number: H175
    Abstract: A sonic converter is mounted in a housing assembly into which a depleted nium rod can be conveniently press fitted and subsequently easily released, for ultrasonic vibrational treatment to reduce residual stress in the rods. The sonic converter is constructed to operate in high temperature environments due to its internal thermal insulation, and an externally connected cooling device. The sonic converter is comprised of a transducer which converts electrical energy into mechanical, vibrational energy, and a horn which amplifies the vibrational energy to the DU rod.
