The results show that, after 1 cycle of α→β→α phase transformation, the original cold rolling texture component (2116)[2641] and the recrystallization texture component (1013)[1210] are almost completely suppressed, and the [2110]∥ ND transformation fibre texture is formed. And after 3 cycles of α→β→α transformation, the [2110]∥ND fibre texture is inherited, and the rolling texture components, such as (2115)[0110] etc, are partially recovered. Afterα→β→α transformation, the microstructure exhibits the typical Widmanstatten lamellar structure, and is also inherited after 3 cycles of α→β→α transformation. The orientation of β phase at 950 ℃ has been measured by HTXRD and predicted by Burgers' relationship with variant selection.(Correspondent: ZHU Zhishou, P.O.
