Texture evolution and slip mode of a Ti-5.5Mo-7.2Al-4.5Zr-2.6Sn-2.1Cr dual-phase alloy during cold rolling based on multiscale crystal plasticity finite element model

•By extracting the interface file of 3D microstructure, a multiscale CPFEM for dual-phase titanium alloy was established.•The relative activity and Schmid factor evolutions of α/β slip systems during cold rolling were quantitatively predicted.•The CRSSs relationship dominated the slip behavior at t/2-t of rolling plastic deformation.•Rotation compelled by the neighboring α grains accounted for the abnormally high strain of very few β grains.
