摘要：

Temperature gradient annealing has been applied to high purity titanium sheet to investigate microstructural and textural evolutions. The annealing with high temperature gradient was performed through a specially designed apparatus for the titanium sheet subjected to continuous cyclic bending (CCB). EBSD analysis revealed characteristic microstructure on cross. section consisting of coarse grained triangular area, in which coarse grains formed inside deeplier at higher temperature side, resulting from higher stored strain and higher temperature annealing, and non. recrystallized fine grained area held at lower temperature. Textural evolution was also examined for the CCBent and annealed titanium sheets. Further, effects of the temperature gradient annealing were discussed.
