PHYSICAL METALLURGY OF TUNGSTEN AND TUNGSTEN BASE ALLOYS
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)
