Ultrafine-grained (UFG) dual-phase (DP) steels containing differentamounts of Ti microalloying element were produced by a new approach utilizingcold rolling followed by intercritical annealing of a ferrite-martensite duplexstarting structure. The DP steels were cold rolled up to 80% thicknessreduction followed by intercritical annealing at 770 °C for 4-8 min to form the UFGstructures. The effects of Ti contents (0.00, 0.06, 0.12 and 0.18 wt%) andintercritical annealing time on the microstructural evolutions, mechanicalproperties, strain hardening behavior, and fracture mechanism wereinvestigated. The results showed thatincreasing Ti content up to 0.12 wt.% decreased the average grain size offerrite (~2.5 mm), while approximately fixed the volume fraction of martensite. furthergrain refinement was not detected in the steel containing 0.18 wt.% Ti. Furthermore, the results showed thatincreasing intercritical holding time up to 8 min enhnaced the martensite island size and the volume fraction of martensite, while approximately unchanged the ferrite grain size up to 6min. Tensile testing revealed intense effect of Ti precipitations on mechanicalproperties. The results showed a promising strength-elongation balance in termsof energy absorption for DP steels (UTS´UE @ 150 J.cm -3 ) compared to both the as-receivedferritic-pearlitic (70 J.cm -3 ). Analysis of strain hardeningbehavior of the UFG DP steels through Holloman analysis showed a continuousvariation work hardening rate response which could be approximated by 2 linearregimes. In all DP steels, the prominent mode of fracture was ductile. It wasalso found that the average dimple size is decreased with increasing Ticontent.
