This report documents and summarizes a portion of the total effort of the Beryllium Extrusion Development Program, Phase I. The work reported herein is part of an extension to Phase I in which the major problems of beryllium extrusion are being thoroughly investigated. Northrop Corporation, Norair Division, the prime contractor, and Nuclear Metals, Inc., the subcontractor, are working in close association to achieve project objectives. Feasibility of unclad beryllium extrusion was demonstrated in Phase I proper, but additional work was considered necessary to perfect extrusion methods. 20-ft lengths of extruded shapes are desired; 5- to 6-ft shapes were made in Phase I proper; 10- to 12-ft lengths of defect-free material have now been realized; and efforts are now being directed toward method development for the 20-ft-long Phase I channel- shaped extrusions. Extrusion H135 resulted in a 26-ft-long extrusion with only a few defects and thus represents the best effort to date. It has not, however, been possible to establish a reasonable degree of consistency. Because of the rather low top speed of the press and the marginal tonnage available at its top speed, efforts are being made to have an exploratory extruding effort performed under Nuclear Metals' auspices at another facility.
