AbstractThe intragranularnucleation of ferrite was studied in a hot strained V-microalloyed steel. By means of torsion tests, the recrystallized fraction was determined for a strain of 0.35 and temperature of 950 °C. Tests at the same strain and holding times corresponding to the start and end of precipitation with subsequent cooling of the specimen showed that the intragranularnucleation of ferrite on VN precipitates leads to a significant decrease in the grain size, close to 50%.
