Microstructural evolution at different cooling rates was characterized by dilatometry combined with scanning electron microscopy (SEM) and transmission electron microscopy (TEM). X-ray diffraction (XRD) and electron backscatter diffraction (EBSD) were adopted to acquire data for dislocation density calculation. The mechanism by which Ti influences the mechanical properties of tempered sorbite was also discussed. The results show that the addition of Ti suppresses the diffusional decomposition of austenite and narrows the high-temperature transformation region of undercooled austenite. The critical cooling rate for the formation of proeutectoid ferrite and pearlite is reduced from 0.5–1°C/s to < 0.5°C /s. Meanwhile, the martensitic transformation region expands, and the minimum cooling rate required to obtain a fully martensitic microstructure decreases. Consequently, a fully martensitic structure can be achieved in the tested steel at a cooling rate of 0.5°C /s. After austenitizing at 950°C followed by tempering at 600°C, Ti interacts synergistically with V to tailor the size and the number of (V,Ti)C precipitates. The volume fraction of precipitates increases from 2.73% to 6.53%.
