Abstract
A program was carried out to secure an improvement of extrusion container liner performance and life for metal extrusion effected in the 2000 - 3400F temperature range. Liner-support tooling was developed to permit use of superalloy, ceramic-coated tool steel, and solid ceramics as liner materials capable of withstanding 180,000 psi stem pressure. The tooling utilized liner-sleeve assemblies which were not shrink-fitted in the container and could quickly be interchanged. Prototype extrusion liners of Rene 41 and Udimet 700 superalloys, and a variety of both Rokide-process and plasma-arc-ceramic coated liners, were produced and evaluated. Compositions of fibermetal reinforced ceramic materials specially designed for liner application, were produced and evaluated by extrusionscreening test. A Rokide-process stabilized zirconia ceramic-coated liner withstood TZM alloy extrusion at 3450F. Plasma-arc coatings of stabilized zirconia, and gradated alumina-nickel, and cast Udimet 700 alloy, proved satisfactory for steel extrusion at 2000F. Fiber metal reinforced ceramic mixtures of 72A12O3-28Mo and 59.5A12O3-40.5Mo proved capable of withstanding billet temperatures of 3450F.
