    Abstract

    The biaxial properties of Ti-6Al-4V and Ti-5Al-2.5Sn were determined at -423 F. Texture strengthening was found to be operative at this temperature, but the magnitude of the increase in strength over uniaxial properties could not be predicted from tension-test techniques for measuring texture strengthening. The strengths of welded joints in Ti-6Al-4V at -423 F were found to be equal to that of the textured parent metal. The dependence of texture strengthening on temperature, strain, and stress state is discussed.
