Abstract An investigation was carried out of the morphology and microstructure of V-Ti complex carbonitride in 09MnVTiN microalloyed steel during reheating under analytical electron microscope. The prior V-rich ellipsoid V-Ti complex carbonitride particles are replaced progessively by Ti-rich cubic ones as the reheating temperature elevated from 1050 to 1400℃. The Ti contents in the core and border of particles increase from 15 and 6% as hot-rolled state into 84 and 94% at 1400℃ respectively.
