| Outline of Final Research Achievements |
Differential speed rolling was carried out on pure titanium (grade 2) to investigate the influences of processing conditions on texture and formability. In addition, for pure titanium with different purities (grades 1-3), normal symmetric rolling and differential speed rolling were carried out to investigate the influence of purity on microstructure, formability and mechanical properties. As a result, proper processing conditions were obtained and the mechanism of texture formation during differential speed rolling was revealed. The sheets processed by differential speed rolling exhibited improved stretch formability for all grades due to relatively isotropic texture and thus weakened planar anisotropy.
