Abstract:

The patent discloses a manufacturing process for a solid or hollow shaft consisting of aluminum or titanium with beryllium reinforcing therein. Beryllium rods are either clad with aluminum or titanium or, in the alternative, holes are drilled in an aluminum or titanium block which beryllium material is thereafter inserted into the holes. The preform with a hard steel central mandrel around which the beryllium rods are positioned is placed within a steel can and heated to a predetermined temperature. Pressure is then uniformly applied to outer circumference of the can to ensure uniform deformation of the beryllium reinforcement. For hollow shafting, the mandrel at the center of the preform may later be removed.
