Information on the consolidation and fabrication processes being used to produce large tungsten shapes and sheet, the general physical characteristics of the various types of tungsten being shaped into rocket nozzles, and the performance of these in solid-fuel rocket motors is summarized. Tungsten has adequate properties to withstand the thermal, chemical, and mechanical environments in many of the more advaneed solid-propellant rocket systems. Tungsten may be used in rocket components in a number of forms, but the leading form is pressed, sintered, and forged unalloyed tungsten. Most of the successful firings of full-scale nozzles at 5500 deg F or higher were accomplished with inserts of this type. An unexpected factor, which may lead to increased use of sheet tungsten, is the good performance of welded metal. (P.C.H.)
