DEVELOPMENT OF DIES FOR EXTRUSION OF COMPLEX SHAPES OF STEEL AND REFRACTORY ALLOYS. Interim Progress Report, June 15, 1962 through September 15, 1962
Significant improvement in the properties of ceramiccoated metallic, metal-fiber-reinforced ceramic, and refractory intermetallic dies, for use in the extrusion of refractory metals and steels, is sought. A state-of-the-art survey was conducted by reference to reports and by visits to experimental and production extrusion facilities experienced in extruding specialty steels and refractory metals. A survey of available materials revealed a number which are potertially fabricable into improved dies. Preliminary choices of material were guided by the agreement of known or predicted properties at various temperatures with characteristics desired in the dies. An indentor device for testing coated substrates was designed and its construction started. Hot pressing furnaces for consolidating the various materials were designed, built, and tested. (auth)
