High-Temperature Texture Strengthening in alpha-Titanium.
Abstract
The high-temperature texture strengthening behavior of alpha-titanium has been investigated over a wide range of temperatures (.30 to .55Tm) and strain rates (.0166 to 0.0000154/sec). The activation energy for creep, was found to be 80% higher than the accepted value for self-diffusion. Cross-rolling samples with a subsequent anneal produced a strong duplex texture. Textured transverse samples were consistently stronger than longitudinal samples, with a 40% difference in strength at the lowest creep rates and in the temperature range most useful for titanium (300 - 500C).
