Abstract: A process is described that includes forming a metal alloy component having a pre-specified three dimensional geometry for use in a nuclear reactor by an additive manufacturing process followed by annealing the formed component at a first annealing temperature within the alpha temperature range of the phase diagram for the metal alloy. A second annealing step at a second annealing temperature lower than the first annealing temperature may be added. Alternatively, annealing may be at an annealing temperature in the alpha+beta temperature range of a phase diagram for the metal alloy, followed by a second anneal in the alpha temperature range of the phase diagram for the metal alloy.

Abstract: A rudder attachment for outboard motors comprising an upright blade or rudder adapted to be removably attached to the gear case or lower end assembly of the motor behind the propeller. The attaching members comprises, in one embodiment, flexible metal straps adapted to be secured together about opposite sides of the gear case and, in another embodiment, metal strips adapted to be secured to the cavitation plate and metal brackets connecting the rudder to the strips.
