A demonstration was made of manufacturing five Copperhead gyroscope components via titanium powder metallurgy techniques. Commercially pure titanium was used for one part the remaining four parts were made of the Ti-6A1-4V alloy, which was produced through the heat treatment of a blend of master alloy powder with the titanium. Two parts were made by isostatic compaction techniques in urethane rubber bags steel mandrels were used to precisely define the interior details. Three parts were made by die pressing followed by sintering. Of these, one was left as-sintered, one was hot forged, and one was subsequently HIP hot isostatically pressed. Test bars representing the different material-process combinations were used to demonstrate that the chosen combination provided adequate mechanical properties for the intended applications.
