Work continued on methods of fabricating and evaluating dies suitable for the high temperature extrusion of steel and refractory metals of complex shapes. Fabrication of ceramic and inter metallic dies by hot pressing and by melting and forging continued. Successful methods of producing tungsten fibers for reinforced dies were developed. A die support system based on the concept of hydrostatic support for the die casing has been developed and shown to be successful in preventing the cracking of brittle die nibs during extrusion.
