Abstract
The alloy titanium-6 Al-4 V has been processed in the laboratory to develop a wide range of textures, and determinations have been made of the yield loci for these conditions. Optical and electron metallography have been used to gain information about the operative deformation modes under various states of stress. Only limited texture strengthening is observed for conditions of tensile loading, although quite significant effects are found in compression. In strongly textured material a large strength differential occurs along thec axis direction, but this cannot be attributed to twinning. It is shown that slip can play a major role in plastic deformation, and that the observed mechanical properties result from the peculiar characteristics of the dislocations.
