Dislocation structures in deformed tantalum were examined using transmission electron microscopy. It was found that the deformation structures formed in tantalum strained at temperatures between 25 and 1000C are comparable to those found in iron on the basis of homologous deformation temperatures. Several observations pertaining to the distribution of tangles at low strains, the types of tangles formed, the mechanisms of tangle formation, and the formation of deformation cell structure from tangles are also reported.
