Abstract:
Extrusion techniques and processes developed at the experimental extrusion facility, WPAFB, Ohio were used to provide wrought materials for other contractors and government agencies. These techniques and processes helped to expedite alloy development programs in refractory metals. Improved lubrication techniques using Corning 7900 glass mixtures were developed for extruding refractory metals at 4000°F. The suitability of zirconium oxide ceramic coated steel dies for extrusion at 4000°F was confirmed. Improved extrusion techniques at the experimental extrusion facilities at WPAFB give reproducible, good quality, round and rectangular bar extrusions at temperatures up to 4000°F and reduction ratios of 9.5 to 1.
