Abstract:

The ten ile properties of polycrystalline tungsten were investigated. Single crystals with a 100 orientation were grown by electron beam floating zone melting. The tensile deformation behavior of these crystals was studied from -196 to 800 C. Single crystals were w rked by rolling and their recrystallization response was investigated as a function of cold work and working temperature. Twin morphology was thoroughly studied. Binary solid solution alloy single crystals of W-Ta were produced by electron beam floating zone melting from compacted ingots. Alloy single crystals containing .25 and 4 tantal m were worked and the recrystallization response was determined to be 400 to 600 C higher than that of worked pure tungsten single cr tals. The tensile strength of sintered and swaged W-TaC alloys was determine at 3000 and 3500 F as a function of alloy composition 0.1-11. Also measured at 3000 and 3500 F were the tensile strengths of the systems W- ThO2 and W-.5 FO2. 9author
