摘要：

X-ray line-broadening techniques were used to establish deformation mechanisms in textured commercial purity (CP) titanium specimens that were rolled at various temperatures. The results indicated that conventional line-broadening techniques developed specifically for polycrystalline powders could be used on textured materials to deduce the slip-system activity and dislocation density that develop during thermomechanical processing if appropriate averaging procedures are followed. The deduced slip-system activity and densities revealed a transition in deformation behavior from a heavily-twinned to an untwinned mode with an increase in deformation temperature for CP titanium.
