Abstract:The ODF method according to Bunge was used to analyse the formation of cold rolling texture in commercially pure Ti sheets with different initial textures.The orientation factor distribution of slip and twinning systems in orientation space was calculated, the stability of {000l} parallel to rolling plane as well as the instability of <1100> parallel to transverse direction were analysed, and the different stabilities of<1100> parallel to rolling direction were discussed. The multiplicity of micro-deformation mechanisms in pure Ti and multiple stable orientations cause remarkable influence of initial texture on the cold rolling texture.
