Weldability, strength, and high temperature stability of chemically vapor deposited tungsten
Three types of CVD tungsten (fluoride-produced, chloride-produced and the combination of the two which is termed duplex) were evaluated to determine their weldability, high temperature strength and structural stability during 5000 hour exposure to temperatures of 1540 C and 1700 C. Each type of CVD tungsten could be successfully electron beam welded but the results for the chloride product were not as satisfactory as those of the other two materials. The high temperature strength behavior of the three materials did not differ greatly. However a large difference was noted for the grain growth behavior of the two basic CVD tungsten materials. Fluoride tungsten was found to be relatively stable while for the most part the grain size of chloride tungsten increased appreciably. The examination of freshly fractured surfaces with a scanning electron microscope revealed numerous bubbles in the fluoride material following its exposure to 1700 C for 5000 hours. Less severe thermal treatments produced relatively few bubbles in this material. Only at certain locations within the chloride material associated with the interruption of tungsten were bubbles noted.

Controlled ferrite content improves weldability of corrosion-resistant steel
Corrosion-resistant steel that adds restrictions on chemical composition to ensure sufficient ferrite content decreases the tendency of CRES to develop cracks during welding. The equations restricting composition are based on the Schaeffler constitution diagram.

Weldability of three forms of chemically vapor deposited tungsten
Methods were developed for electron-beam welding several forms of chemically vapor-deposited tungsten. Weld ductility was evaluated from the results of ductile-brittle transition-temperature determinations. Welds in tungsten produced from WF6 were considerably more ductile than those associated with WCl6-produced tungsten. The larger grain size of the latter material was largely responsible for this behavior.
