Abstract

By means of three-dimensional crystallite orientation distribution function (CODF) analysis, the relationship between texture control processes and mechanical properties anisotropy in titanium sheet has been investigated. The formation and transition of cold-rolling texture, recrystallization texture and phase transformation texture are also discussed. The results show that, after being cold rolled unidirectionally and annealed, titanium sheet exhibits a strong anisotropy of mechanical properties due to the pyramidal textures ((2) over bar 115) [0 (1) over bar 10] and ((1) over bar 013) [1 (2) over bar 10]. After a cyclicphase transformation process coupled with cold rolling and annealing treatment, the recrystallization texture component ((1) over bar 013) [1 (2) over bar 10] is suppressed and Ch ki II II ND transformation fibre texture (where ND is the sheet normal direction) are developed, which produce a well improved mechanical anisotropy. The cross-rolling process can create a basal type texture (0002) [uvtw] or a near basal type texture, which leads to low level planar mechanical properties anisotropy but to relatively high normal plastic anisotropy (R value).
