Web[en] Twinning activity of pure titanium during rolling at room and cryogenic temperatures was investigated by electron backscattered diffraction (EBSD) technology. Because cryogenic temperature facilitates twin formation, cryogenically processed samples exhibited greater hardness than those processed at room temperature. WebExperiments The rolled commercially pure titanium T40 sheet (ASTM grade 2) with the thickness of 1.5 mm was annealed in a vacuum furnace at 800 C for 3 h. After annealing, the sheet was fully recrystallized with an average grain size of ~200mm and no twins appear.
