This report includes Battelle Memorial Inst., Columbus, Ohio. DEVELOPMENT OF NEW OR IMPROVED TECHNIQUES FOR THE PRODUCTION OF TUNGSTEN SHEET. A STATE-OFTHE-ART SURVEY, by D. J. Maykuth, V. D. Barth, and H. R. Ogden. 29 Dec 60, 1v. illus. tables. Subcontract to Universal-Cyclops Steel Corp., Bridgeville, Pa., Contract AF 3360041917A state-of-the-art survey of W sheet rolling was completed. Industry capabilities as related to raw material availability, consolidation practices, and conversion methods were analyzed. Domestic tungsten sheet is available in sizes less than one-half the width and less than onefifth the length of that desired. The survey indicates that two consolidation techniques should be initially followed, i.e., arc melting and powder metallurgy. For the arc-cast work pure tungsten is recommended as the alloy, while for the powder metallurgy work K-100 powder is recommended. Several conversion techniques will be employed for initial breakdown of the as-cast structure. The survey indicates that the arccast material should be extruded and then forged or rolled directly. However, preliminary data indicated that direct forging can be accomplished and should be investigated.
