The recrystallisation-stop temperature (RST) of vanadium microalloyed steels containing 0.20 and 0.43 wt% V was determined experimentally by single pass rolling in the austenitic phase field. Conventional Controlled Rolling (CCR) of each composition was simulated by rolling of reheated slabs, whereas Hot Direct Rolling (HDR) was simulated by rolling as-cast 0.2 wt% V austenite directly after it solidified. The experimental recrystallisation-stop temperature of the HDR and CCR austenites containing 0.2 wt% V were similar, despite a large difference in grain size (92 μm compared with 1150 μm) and process routes. The RST model, proposed by Dutta and Sellars for niobium steels, was modified to suit the current materials, process routes and experimental methodology. The original model overestimated the experimental RST of all the three steels studied. However, good agreement was found between the modified model and the experimental RST of both the as-cast and reheated austenites. The initiation of recrystallisation was more rapid in V austenite than in Nb austenite, and not so strongly dependent upon grain size as proposed by the Dutta and Sellars model.
