Abstract: The influence of cycle phase transformation α→β→α process on the texture transition and yield stress anisotropy in cold rolled commercially pure titanium(C. P. Ti) sheet was investigated by using the crystallite orientation distribution function(CODF)analysis. The results show that after three cycles of phase transformation, annealing texturs component(1013)[1210]is almost suppressed and the main transformed texture consists of a [2110]‖ND fibre texture (ND means the sheet normal direction) and several basal orientation peaks such as ( 0002 ) [3210]，(0002) [1320] and (0002)[2310] etc. And the original rolling texture (2115)[0110] is developed into a partial [2115]|| ND or[ 2117]||ND fibre texture. All these transformed orientation features provide the lowest anisotropy yield stress.
