Abstract Scope Twinning induced plasticity (TWIP) and transformation induced plasticity (TRIP) play an important role in determining the ductility of beta titanium alloys. However, the microstructure evolution during the deformation and the mechanism involved in the TWIP and TRIP in beta titanium alloys remain controversial. In this work, the microstructure before and after the cold rolling of beta titanium alloys, e.g., Ti-24Nb-4Zr-8Sn (wt.%, Ti-2448) and Ti-5Al-5Mo-5V-3Cr (wt.%, Ti-5553), were systematically investigated using scanning electron microscopy, transmission electron microscopy and aberration-corrected scanning electron microscopy. Nano-scale metastable athermal omega phase and O’ phases were observed in the beta titanium alloys before deformation. Hierarchical twinning microstructure, including primary {332}<113> deformation twin and secondary {112}<111> deformation twin, was characterized in Ti-2448 in detail. Interestingly, various metastable phases were observed at different twin boundaries. In addition, a novel {10 9 3} <331> type deformation twin characterized in the cold-rolled Ti-5553 for the first time will be introduced.
